Health Concern of German Shepherd

Question
I have a 5 month old GSD and he weighs 65lbs which the vet said he is in perfect shape and is not over weight, just going to be a big dog. But, right now has diarrhea it is off and on throughout the past couple of weeks. I was wondering why this is? We changed food and is still the same thing.

Answer
Try this 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.  

If he hasn't stabilized by the first of the week, call the vet.

Once settled down, start replacing it with an adult chow over a few days.  An early switch to an adult chow slows growth and gives sturdy joint more time to develop.  he will still be a fine big boy, it will just take a little longer.
