Good grief. Why would you give your dog those as treats?

You don’t need to give it to them, they just graze at the conveniently provided buffet.

Truffles come to mind.

One thing I'm not following is how the side/order bias is being handled. OP measures a IMO very large bias towards left-hand treats, but it is unclear how that is handled (ahem)? Skimming https://github.com/adamwespiser/best-dog-treat/blame/main/an... doesn't help me understand if it is being modeled as a covariate to adjust for the bias or if it was dealt with by construction (eg. by always offering pairs twice, swa…

I suspect it’s by construction, looks like they’re offering every permutation of treat choice twice. Below, I filtered for A vs E, the top two choices. Notice how they switch left and right hand each time: A/E :: A E/A :: A A/E :: E E/A :: E A/E :: E

Author here, yes, that's correct.

The initial set-up was to do 3 comparisons of the 5 treats (30 trials), alternate between right and left hand, then write a quick python script to randomize the order.

A bit more than halfway through the experiment, I ran the model and realized that A/D/E were the only contenders left, so I removed the B/C trials and added more A/D/E trials.

Add some interesting smells and dogs will eat absolutely anything. Used tampons, literal shit, soiled underwear, dierhia, dead bird, freshly killed cat, they owners... It is basically a pig with collar that lives in your house.

* varies by breed I've seen many a lab eat their own shit, but my standard poodle takes his time investigating even a piece of steak before he decides whether it's worth eating.

Varies by personality too.

This makes me wonder what the research is for whether certain types or breeds of dog prefer certain dog treats, and how individual dogs might develop a preference for one kind over another. Based on this experiment it doesn't seem like the type of meat matters much, since while the top ranked treat is chicken, his second favourite seems to be the duck one.

We have 4 smaller dogs (mix of chihuahua and terriers), and they all absolutely love the greenies over anything else. One of them now has a prescribed treat and he definitely isn't happy about it, and the others won't touch it.

Hardest part is now feeding them all separate dishes at regular times every day.

Some dogs have a strong preference on right/left. I've known at least six dogs that will only shake hands with their left paw.

Or cat turds

Kitty roca confirmed. Our Husky was a goon for it. At least it forced us to keep the boxes clean several times a day.

Kitty Roca is both the best and most awful thing I've seen in ages.

There is a medicine you can put on dogs' food to make their crap taste bad to them. There might be something similar you can give kitty.

Yes, and also the presence of a window fan on that side is a big deal because the selection is based on scent. In my experience dogs appear to "like" a scent based on how strong it is, not necessarily how it is "flavored" (for examples, dogs can behave as if they love the smell of poop or skunk spray, but it's actually the powerful sensory information that they're reacting to, not a culinary desire). It seems possible to me that the dog is choosing whichever scent is more powerful.

I liked that the post surfaced the bias instead of quietly ignoring it
