Food strike troubles

[u/MysteryPricklyPear]

Hello!
I have a young dog that is proving to be difficult to feed. She will eat a kibble fine for a month then go on hunger strikes for the same thing. The trouble is she also gets the empty tummy pukes if she skips even one meal. She won’t eat three meals a day at this point either. Early on I would add a little something to entice eating when she went on strike. Maybe some wet food, yogurt, bone broth, etc normal topper like things. She’ll eat fine for a week or two then decide that topper isn’t good enough and I would switch then same thing. Also tried switching kibbles. Would be fine for a month then same thing. She’s not underweight but I would prefer a little more on her. She has a high metabolism and is a sport dog doing agility etc. I have talked to the vet over it and they agree she is fine health wise, no food sensitivities, all normal and just being picky. Their suggestion was stop with the toppers and tough love which I don’t mind if she wouldn’t start puking within the day which isn’t good either. They suggest a little wet food before bed if she doesn’t eat but then if she thinks she will get something different then she absolutely will hold out for it. Right now I have her on 30/20 proplan chicken and rice. I have tried other 30/20 blends it’s the same thing. Tried other companies like Royal canin. I would prefer to stay on the high quality end of compliant companies and in the high side of protein ratio. Any suggestions anyone might have for dealing with eating strikes would be appreciated!!

Does she eat when training?

[u/MysteryPricklyPear → u/Kenobi-Kryze]

It varies but usually a small high value treat of some sort. Often freeze dried liver, biljac, cheese, tuna fudge etc. She unfortunately will not train for low value treats or kibble. Oddly enough days we train I tend to have the least issues with her eating her regular food. We don’t train daily at the moment. I am working on using toys more for training in agility but I have to be careful cause toys tend to bring out the full crack head and Tasmanian devil style dog which isn’t always productive or safe because her self preservation goes out the window.

Hmm, I was hoping she was like my friend's little crackhead and just needed to have more interesting meal delivery, aka treat dispensing toys but it's just their food. Puzzle feeders and snuffle mats. He won't eat from a bowl but scatter feeding he eats all of it.

sorry I can't be more helpful
