RE: I regret getting a puppy and I don't know what to do.
I too am sorry for the position that you are in. Seems like a dead end, huh?
The problem is not the innocent little pup. The problem is you and your boyfriend. Not to be harsh but if the two of you are not at a place in your relationship where you can maturely discuss the pro's and con's of such a commitment then there is a big problem.
There are always factors involved in getting pets and committing to their forever care. It is apparent that this was not discussed and was a "spur of the moment" decision. Ultimately the one to suffer is the animal unless one of you decide to be grown-ups and handle this situation properly. Dr. Phil would be able to handle this better than a pet lovers forum.
I mean no harm in my harsh words but I do not feel the need to coddle people who have made decisions at the detriment of an innocent pup that didn't ask for the apparent crap that it has been tossed in to.
