Neighbors dog has trouble pooping.?

It sounds like a blockage take it to the Vet.

Unfortunately by letting your dog run out of control in a public place and trespass onto private property you are laying yourself open to fines. I think they were within their rights to hold the dog until Animal Control arrived to collect it. I think all you could sue the neighbour for is littering, if the dog poop was not from your dog. If his fence marker string was on the actual border between the properties then that too was OKL. The only time it would not be is if it was a shared drive or yard or where vehicles had a right to turn. This is a typical neighbour dispute which has started to run out of control. You either put up with it, build dog proof fences or move sell/rent somewhere new.

More fiber!

haha

Seriously, just like people, give him a fiber chew (not the choco kind...obviously).

Also, and this is not something I do, but you can take a match, get the tip wet and stick it in his little butthole. The breeders I know have done this with pups who have a hard time pooping because the sulfur is like an enema.

Hair ball treatment for cats can be used as a laxative for dogs.

You can try canned pumpkin. Not the pie filling one that has spices though, just plain pumpkin.

Um... laxative? I take it three times a day.
