A sweet potato for a fussy little girl no more 😁
I have a little Jack Russell and she is a fussy little thing😂 I’ve gone through so many treats that she won’t eat but when I found these treats, she loves them and that’s all I have to go off of is that my fussy little dog loves these treats,so to me they’re a good treat, but that doesn’t mean every dog is gonna love them so I just want to make that clear. I hope your dog will enjoy them the way my little girl does.😉

Dogs love these sweetpotato treats
Flavor Name: Sweet Potato, Size: 2 Pound (Pack of 1)
We dogsit grandkids’ dogs. Grandson sent a half bag of these and a full bag of another brand of Sweetpotato treats. The dogs actually spit out the new brand and refused to eat them. We have a tiny dog, a middle dog and a big dog. They ALL went crazy over thesetreats. They are very healthy treats. Works for all size dogs. The bag tells how much to feed each size dog? Grandma was the treat lady so I won big time ..We were worried cuz we had never watched the dogs before. We actually had a great time and hated to see them go.They really looked forward to their treat time. 😋
