Why does my dog have a hard time with bowel movements?

My four year old Chocolate Lab seems to have constipation, I think. . What can I do for him?

Hello, Our two dogs are away on vacation with us in a new environment. They have not had a bowel movement in three days although they are eating well and drinking well. They are urinating regularly and still have the same playful demeanor. They are running, playing and eating well. Please advise.

How do we avoid constipation in our dog? Is there a food you prefer for Miniature Dachshunds?

I have a Border Collie-Lab mix. He is two years of age. I am having troubles with him chewing and eating towels. He is eating alot of grass and has a hard time pooping. What can I do to clean him out and stop the eating of towels?

My 7-month old Golden Retriever is occasionally constipated. We have been using Purina® Puppy Chow® Balanced Nutrition Formula and also Purina® Puppy Chow® Large Breed Formula. We also feed occasional table (protein) scraps, but we try not to overdo it. Any suggestions on what to do?

My dog is away with me for the weekend in a strange environment and she has not had a bowel movement in 2 days. When I took her for a walk her hind legs appeared to be too weak to support her and we had to stop and let her rest. This happen several times while on the walk. Do you think this has anything to do with her failure to have a bowel movement or do you think this has to do with some other problem?
