15 month old Chocolate Lab

Question
Good Morning,
We have a 15 month old Choco. lab.  He his crate trained, recently though he has started whining in the middle of the night, and needs to go outside to the bathroom. Within the last couple of weeks he has been going (poop) allot more frequently and urgently.  Stool can be a little soft.  He was at the vet end of May for Heart worm, was given clean bill of health.  He is very energetic, and eats well.  Not sure if you have any experience with this. IF it could be a diet issue (haven't change food), heat thing (doesn't like it), allergies (?).  He gets two meals a day morning and evening, with a snack in the afternoon (4 cups total)  He is not over weight.  Thanks

Answer
it is possible he has foraged something that upset his digestion or picked up a bug.  If he hasn't cleared up by next week, better check with the vet.  

You could try a bland diet too.  

If a dog is having trouble keeping anything down or continuing diarrhea try this out of the manual I have from a large, knowledgeable dog guide school.

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 diet they need long term. I have seen it work.
