Teacup poodle Feeding

Question
I have a 10 week old teacup poodle, and it seems that we cant find the right food for her.  Really soft stools unless she has to wait more than 4 hours to go poop (waiting in her crate)

So far we have tried Pro plan for puppes, and Authority For puppies (both kibbles and Canned) with little success (both lamb and rice formulas).  Next i think that i want to try Eukanuba but i was wondering if you had any specific reccomendations.

Thank you

Answer
Most dogs will do fine on most chows.  Jumping around from chow to chow is one of the worst things you can do, especially if you make the change too rapidly.  Usually changes of chow should be done gradually over a week.  Otherwise will CAUSE loose stools.  Maybe firm her up on a bland diet.

 
Bland recovery diet for dogs.

3 parts cooked rice, one part boiled hamburger or chicken, or cottage cheese. I think you can substitute boiled potatoes for the rice.  Once in an emergency, we bought a plain baked potato from Wendy's.  

This is meant for short time settling a dog's digestive tract.  It is not the complete and balanced they need long term.  

Once you have her firmed up, reintroduce one of the chows you have tried, or go to the Eukanuba.  if she doesn't firm up on the above diet, likely she has a physical problem, cocosilious or something.  See the vet.
