Reconsider - and get a rescue animal
Hi, and welcome.
Just like anything else, there are many different reasons for pets to be at the shelters/rescues. Not all are bad, not all are stays and some are just there because of an unfortunate event such as their owner moving and not being able to take them/it along and sometimes it is due to the death of the owner....sometimes allergies...you name it. Most shelters will give you their opinion of the animal after they observe it for several days. When you see an animal at the shelter, please remember how much stress the poor thing is enduring by being there and really look beyond some minor behavior problems. Just look for the traits you may want in a dog/pet and ask lots of questions.
Don't get me wrong, there are lots of nice breeders out there too, but there are lots of wonderful doggies in need of good homes at the shelters and rescue places.
Good luck, welcome and keep us up on what you plan on doing about the loss of your doggie.
