Quinn will work for everything and anything, but some higher value treats I like are dried beef lung, soft and chewy Cloud Star treats, hotdog, and the soft Rollover roll you can cut/break up.
Chloe is obsessed with carrots. But she'll eat anything. Seriously. Although she isn't a huge fan of popcorn (probably the texture). But she'll eat it!
Violet loves fish oil pills. She FLIPS when she hears them shake around in the bottle. She also LOVES apple and can hear when you're cutting one up and will run into the kitchen!
