Good treats to send home with pets?

I always make note of a dog's particular food preferences or allergies, and am careful to point out that everything in the dog's goody bag is x-free (x being whatever it is they avoid) when I give them to clients. Just putting that thought into it makes a lot of owners happy, even if the treats aren't something they would normally buy. I also ask new clients what types of treats their dogs are allowed, so I can avoid giving them anything they can't have. Just making it clear you've put thought into it and listened to the owner's preferences about their dog's diet is a great way to end a stay.

I also get a lot of bulk treats at Costco. They're not the highest caliber, but they also aren't bad. They also sometimes sell big packs of dog bag rolls that come with a couple bone-shaped dispensers. These also make good goody bag gifts, since everyone needs dog bags. Another great place to get goody bag stuff is pet expos. You'll get a ton of samples of high quality treats and foods that you can re-gift. Pet shops will also give out samples (or sell small sample bags) of a lot of foods, which make good treats as well. You can also make homemade dog treats, which have the added touch of being very personal. There are tons of recipes out there, and somewhere in the archives here, people shared their favorite recipes.
