Canine Meals Toys, Charges of Reinforcement, and the Matching Regulation

Three dog stuffable food toys: a blue Westpaw Toppl, a red Kong, and a Greenish-yellow Westpaw Tux

Are you able to inform which some of the meals toys within the photograph above most likely provides the absolute best fee of reinforcement when complete? Your canine is aware of!

Lewis taught me this lesson. He’s glad to lick and munch on a Kong (middle) filled with frozen meals when there’s not anything else occurring. But when he’s excited within the automotive, he’ll forget about a Kong filled with the similar meals. It’s now not prime sufficient price in that scenario, however the similar meals in a “Toppl” toy (left) is.

What makes the variation if the meals is identical? It’s the velocity of reinforcement. The velocity from those two toys is vastly other. That is on account of the bigger to be had floor space of the Toppl and the loss of the “bottleneck” impact of the Kong.

Any other issue that has effects on the velocity of reinforcement is whether or not the meals is frozen. Frozen meals is slower to come back out of the toys. Lewis has additionally demonstrated that cool or room temperature meals is extra engaging, because it raises the velocity of reinforcement even upper.

Those are very elementary observations, however I had by no means considered them systematically ahead of.

Meals Toys and the Matching Regulation

Toys range within the accessibility of the meals on account of their design and mechanics, and canine should ceaselessly carry out more than one behaviors to get the meals out. In case you watch your canine devour out of a meals toy from starting to finish, you’ll see nice examples of the matching legislation.

The matching legislation tells us that we (animals together with people) carry out behaviors in a ratio matching the ratio of to be had reinforcement for the ones behaviors. Meals toys can provide us real-time examples of a canine converting behaviors to optimize what will pay off probably the most at any given second.

It’s very best to grasp with two toys full of the similar meals. If a canine can get meals out of Toy A miles quicker than Toy B, they are going to empty maximum of A ahead of they transfer to B. They are going to transfer when B’s fee of reinforcement turns into upper than A’s.

However we will be able to additionally see it with one toy, as a canine adjustments their conduct to make use of top-of-the-line one at that second to get the meals out.

Meals Toys and Operant Finding out

Let’s again up a bit, as a result of we may not be conversant in serious about operant studying relating to meals toys. We typically suppose on the subject of coaching: people giving cues and the canine responding. For example, my canine cross to their mats once I cue them to take action as a result of I’ve given them meals masses of occasions for that conduct.

How is a meals toy like that? A meals toy supplies cues, too! Those visible, audible, kinesthetic, and olfactory cues point out there’s meals within and what sort of of it there’s. The toy ejects or permits get right of entry to to meals due to other behaviors the canine plays. The velocity of reinforcement adjustments all through the method, relying on how a lot meals continues to be within the toy and different elements. The matching legislation is available in because the canine varies their conduct for optimum reinforcement at each and every degree because the toy empties.

Each and every this type of meals toys calls for a special set of behaviors to get the meals out

It’s the similar with an open bowl of meals; the method simply is going so much quicker. The velocity of reinforcement is far upper at first when the canine can take giant bites of meals than it’s on the finish when there are just a few items left, then crumbs. There are nonetheless more than one meals gaining access to behaviors. Those come with:

* strolling to the meals bowl;
* scooping up the meals with their mouths;
* licking the bowl; and
* in search of spilled meals outdoor the bowl.

Each and every canine who eats out of a bowl is “meals motivated.” It’s simply really easy paintings, for many.

Maximum meals toys observe a an identical reinforcement development: the velocity of reinforcement is upper at first than on the finish. A couple of have a “hump” of issue to recover from originally, then a prime fee of reinforcement that tapers off just like the others. I have reviewed a toy known as the Foobler that deviates from this conventional development sufficient that it will confuse or frustrate some canine.

I’m going to supply some observations I’ve made about various kinds of meals toys: their charges of reinforcement and my canine’ behaviors in reaction.

Wobble Toys: The Kong Wobbler, Nina Ottosson Pyramid, and Others

Those arduous plastic toys have a weight at the backside and switch themselves upright after motion like inflatable punching baggage. Meals spills out of a hollow after they tip, so canine discover ways to push them with their noses and manipulate them with their paws to make that occur. The velocity of reinforcement adjustments relying on how a lot meals is within the toy. If there’s, say, a part a cup of kibble within the toy, nearly each and every motion goes to knock some out to start with.

The behaviors I’ve noticed canine carry out to get right of entry to the meals are:

* drawing near the toy;
* knocking the toy over with their paw;
* pushing the toy over with their nostril from the highest of the toy (uncommon; I’ll give an explanation for why);
* pushing the toy from the ground with their nostril;
* rolling the toy on its facet in a circle with their nostril;
* in search of kibble that can have scattered away; and
* coming to me for assist with the final bits.

If pissed off or left too lengthy with the toy, a canine may additionally chunk on the opening or the place items sign up for.

To start with, the canine is also consuming continuously for a few mins. However because the toy empties, it takes extra paintings, extra actions to get each and every piece of meals out. On the finish, there is also two or 3 intransigent items of meals that require a number of mins of labor to get right of entry to. The velocity of reinforcement may be very prime at first, slows down because the canine should paintings more difficult to get the meals, then may be very low on the finish when there are just a couple of items left. A canine with much less revel in or who isn’t hungry may surrender and depart the ones final items of kibble. It may not be definitely worth the effort. My canine be informed that I can select up the toy and assist them with the ones previous few items.

I hadn’t discovered till I watched the video that Clara has a chain of behaviors she typically makes use of with a Wobbler toy. First, she knocks it over along with her paw. Then she pushes it in a circle along with her nostril. If she pushes the toy along with her nostril when it’s status, she pushes the bottom. Her approach prevents the toy from punching her within the nostril.

My spouse’s small canine both were given punched within the nostril or noticed the danger of it. I presented her to the smaller Wobbler. It has a proportionately heavier weight within the backside and the motion is stiffer. It’s more difficult to push over and is derived again up extra forcefully. After a few pushes, she would now not engage with it. We switched briefly to another form of toy, and I filed that bit of knowledge away for long term reference.

Rolling Toys

Rolling toys have a reinforcement agenda very similar to the wobbler sorts. A large number of meals comes out to start with, then the quantities diminish because the canine rolls the toy round. I’ve spotted that after the velocity of reinforcement will get low, Lewis will take a wreck and scout round for any kibble he can have knocked out ahead of and now not spotted. Matching legislation! He would possibly get extra items of meals in 20 seconds of scouting the realm than in 60 seconds of pushing the almost-empty ball round.

The meals in quest of and gaining access to behaviors I’ve noticed Lewis doing are the next:

* discovering the ball (I range its placement);
* pushing the ball along with his nostril;
* rolling it along with his foot;
* wearing the ball to another position;
* leaving the ball and looking the realm;
* when indoors, attaining underneath closed doorways to check out for kibble that escaped; and
* sitting by means of those self same doorways to get me to open them.

I concentrate when he carries the ball. He would possibly do it to get the ball to a extra optimum space, say, clear of some other canine who’s giving stink-eye from the opposite facet of a child gate. However wearing can be a precursor to looking to chunk up the toy. That occurs particularly when the velocity of reinforcement will get low. This, too, displays the matching legislation. The time it takes to get the ones final couple of items of kibble out will also be very lengthy, however chewing will also be reinforcing in itself and will occur instantly. And who is aware of, it’s possible you’ll get to the kibble that means. (I confiscate the ball at that time, buying and selling a couple of items of higher meals for it.)

Gentle mannered Summer time ate out of the Difficult Deal with ball for a lot of her existence and not attempted to chunk it up. She were given each and every piece of meals out, regardless that. She cherished the toy; she discovered its title and may just in finding it on cue. Right here’s an lovable video of that for the Summer time lovers.

Clara, then again, chewed nearly each and every toy I had when she was once a teenager, ahead of I discovered to oversee her higher. The one toy that proved impervious was once the Ottosson pyramid.

Snuffle Mats and Meals Scattering

Snuffle Mats have reinforcement schedules very similar to the ones of the previous toys. The velocity of reinforcement is richer at first, then thins out as there’s much less kibble to be had and extra looking vital. However in my statement, they’re more straightforward than maximum different toys at first and on the finish, and the velocity of reinforcement doesn’t alternate up to with the wobblers or balls. The meals is extra obtainable normally, even to an green canine. There’s little manipulation concerned; it’s most commonly the nostril!

Scattering meals at the ground round the home or at the flooring outdoor generally is a an identical workout. However in the event you scatter it lightly over a big space, there received’t be a prime fee of reinforcement at first. Even supposing discovering meals at the flooring is one thing maximum canine be informed simply, it will pay to make this workout quite simple to start with. If I have been to unfold a part cup of kibble over my again backyard as my pet’s first odor workout, they’d surrender speedy. The velocity of reinforcement could be low to begin with and fall to 0 in the event that they didn’t transfer out of the unique space, which they wouldn’t know to do. Their meals in quest of conduct would cross into extinction in that scenario. You’ll get started with a space of a couple of sq. toes (an invisible snuffle mat), then magnify it because the canine good points ability and an working out of the sport.

I discussed above that Summer time cherished her Difficult Deal with Ball. What does she let us know on this video in regards to the differing charges of reinforcement between the ball and a snuffle mat?

Sound alert: there are jingling tags within the video.

Toys for Cushy Meals: Kongs, Westpaws, and Others

Those container kind toys will also be filled to be really easy (prime fee of reinforcement from the very starting) or more difficult. In case you have by no means used this type of toys, take a look at my video, “Kongs for Inexperienced persons.” It’s simple to make those toys too tough to start with. Additionally learn additional on this put up, as a result of I made that video in 2012; there are actually a lot more straightforward toys of this sort to begin with.

When first introducing those toys, use very yummy meals at room temperature so the canine has quick get right of entry to to it and will be informed some strikes for manipulating the toy. However as a result of freezing them will increase the variations within the fee of reinforcement, I’m going to talk about frozen ones.

Now we’re going to revisit my opening level: toys with larger openings have a better fee of reinforcement for the canine.

An orange Westpaw Toppl and a red Kong food toy, both filled with canned dog food. The opening to the Toppl is much bigger than the opening of the Kong.

Even supposing the orange Topple within the photograph accommodates extra meals total, that’s now not an important level. The outside space is greater, and extra meals is out there than within the Kong, despite the fact that the canine can simplest lick it. The velocity of reinforcement relies on the dimensions of the outlet, what behaviors can be utilized to get the meals out, the velocity of thawing, and the dimensions of the canine in comparison to the dimensions of the toy. Initially, the canine can lick on the meals and scrape their backside enamel at it. Because the meals thaws, the toy turns into extra versatile and extra chewing strategies are conceivable.

The Toppl begins off with a reasonable fee of reinforcement when frozen. The canine can lick, scrape their backside enamel towards the meals, and chunk on the rim space with their best enamel. There’s extra space to get their enamel in. A large number of the meals is uncovered to air and will thaw beautiful speedy. Because the meals thaws, the velocity of reinforcement accelerates much more, till the tip the place it slows down as they get the final bits of meals out. The Kong, then again, begins out arduous. The meals opening is small, and the frozen cast toy provides little get right of entry to to the meals. It thaws slowly because the canine to start with can simplest lick and scrape their enamel towards the small opening. There is also some energy chewers who can overwhelm a frozen Kong of their enamel so the meals crumbles and is derived out quicker. However even for the ones canine, the Toppl would most likely nonetheless be more straightforward.

Canines can construct some attention-grabbing abilities with Kongs. But even so licking on the contents and chewing across the hollow, some canine discover ways to toss the Kongs within the air so the contents will loosen and fall out.


* Apply your canine with a meals toy and depend the other behaviors. It’s a laugh and you’ll be informed one thing.
* Look ahead to true enjoyment. Simply because one thing is named a meals toy doesn’t imply a canine will revel in it, or revel in it at that second.
* Be careful for frustration. No longer simplest is it ugly for the canine when behaviors forestall running (cross into extinction), this case predicts that the canine’s conduct will range extra. That is when they may get started chewing the toy relatively than running to get the meals out. So watch carefully when they’re completing up the meals.
* Supervise, supervise, supervise. Do higher than I did with Clara. Chewing arduous plastic will also be unhealthy; swallowing it may be deadly.

I plan no less than two extra posts on canine and meals toys: one on contrafreeloading and one on whether or not licking is intrinsically extra calming than chewing.

I’d love to listen to about your canine’ distinctive approaches to meals toys!
