Disliked by Dog

I wish I hadn't bought the 12-lb bag right away! We switched our one year old pup from the puppy version of this kibble to the adult - sticking with the salmon protein

I wish I hadn't bought the 12-lb bag right away! We switched our one year old pup from the puppy version of this kibble to the adult - sticking with the salmon protein. We gave him a few weeks transition and he will not eat the kibble and can somehow tell the difference between his old kibble and new to the point he eats around it. I learned my lesson and will order the smallest bag, first, before committing to a big bag of any kibble. Our dog is a picky boy!!

My order was delivered, but not to my door. I live on the third floor and have suffered a knee injury which severely limit's my mobility at the moment. I was notified of the delivery, but only saw the package because I was walking my dog and it was downstairs on the other side of my building. It was a large, heavy bag of dog food and I had to haul it across the building and up three flights of stairs with a bad knee which caused more pain.

My English bulldog has never had a solid poop in his life. We were having to give him supplements everyday to firm up his stool. I started this food and once he fully transitioned he has never had a soft poop since. No more having to wipe his butt Everytime he comes in. He is happy and so am I.

I’ve tried other kibble but my dog really likes this.

I’ve been back and forth with a Purina brand and Hills, and my dog prefers this best mixed with some broth and canned dog food.

Leaving it behind

We are trying to transition our border Collie from puppy food to adult dog food. He just eats around this food, we tried chicken and salmon, leaving it in his dish

We are trying to transition our border Collie from puppy food to adult dog food. He just eats around this food, we tried chicken and salmon, leaving it in his dish. I've tried adding Portland Pets toppers and egg and shredded cheese and he still leaves the adult food behind. I hear some found that their dogs preferred the lamb but I haven't seen that option in a small bag yet.

Well liked by both dogs

A Frenchie and Lab mix both liked this. It also improved their poop. Glad to have the salmon for the Frenchie, even though it contains some chicken products it

A Frenchie and Lab mix both liked this. It also improved their poop. Glad to have the salmon for the Frenchie, even though it contains some chicken products it seems to be a better formula than the chicken only formula for him.

My dog loves this food

He has a very sensitive stomach and this is the only food that doesn’t “upset his stomach”. He goes crazy for it.
