I buy Bil Jac treats occasionally, I know they're not healthy but I feel he deserves a yummy treat every now and then! He eats healthy most of the time.
Plus, I love that they are perfect for training (size-wise) and he obviously LOVES them. Also, they are cheap! I do buy Zuke's too but lately Jackson has gotten picky with those and doesn't seem too interested- so not a great motivator for training!
Here's some more great options for training treats, some of them being healthy, some being okay, and some being bad.

Lately, I've been using these "Real Meat" brand treats. They are 95 percent meat.

Jackson goes crazy for them and they have all kinds of different flavors. I typically try to stick to mostly all meat treats or those freeze-dried liver type treats.
