My boys love their treats and will usually come running if I say the word. They get treats for coming in when I call them in from outside. I have them trained to come when I knock on the back door window. They also get lots of treats at agility class where I feel like the PEZ dispenser of treats. I try to get healthy treats but sometimes they get junk treats too. For a while Costco carried Alligator Treats, made in Louisiana from real alligator meat, and these were especially favored. They were very stinky! I have rarely made homemade treats and they are also very popular. But they are not picky. They love all treats.
