I have a 4 month old labrador who has has runny stool (liquid mainly) since day 2/3 or getting her. When she arrived from the breeder she was fine.
We weaned her off the Hills (from breeder) and onto Orijen to match our other dog. We tried the plain boiled rice diet but every time we got her stools vaguely normal (it normally took about 7 days of just rice) we'd add a teeny wee bit of biscuits and the liquid poo returned.
This was a recurring cycle and she's never had solid stools. The vet is not concerned as she is gaining weight as he'd expect, and she isn't 'down' or lethargic or anything odd. The only thing is this liquid stool. You'd never know otherwise that there was a problem.
We recently had her in kennels and the owner said he was confident that the orijen was the problem. He said as its about 40% protein its waaaay to much for a dog (even though this is the puppy specific food) He put her back on Hills for the week and claims her stools were pretty good. He gave us some Hills to take away.
We got home, and her stools were all runny again. She's been home for 3 days now and stool back liquid (this is on the Hills still)
We don't see Hills as a permanent solution as it doesn't rate high like orijen on the dog food analysis sites. Anyway her stool is liquid. Jets of liquid.
We're going crazy with trying to work out what to do. I've ordered some fish4dogs as its lower protein than Orijen. But is high protein really the cause of diarreah? The dog is up needing to go out 3 or 4 times a night. We're tearing our hair out. I need my sleep. please help!!
