Yes, I have had to help with that decision. It is never easy. My daughter is special, and wheelchair bound. We tried adopting several dogs when she was young (6 months old) but many were too quick, aggressive, or just did not fit. We located a Cocker at the local pound. Not very healthy looking, abused, dirty. She had just arrived from a rescue mission. We brought Buffy home, shaved her, cleaned her up, and brought her to meet my girl. Buffy made a lap or two around the house, and plopped down next to my girl. They seemed to take to one another. We kept Buffy overnight, and things went well- very well. We took Buffy to the vet for an exam and shots. Our vet said Buffy was OK, but were we aware she was chipped? He scanned the chip, and called the owners. Seems Buffy was a purebred Cocker from a reliable breeder near Chicago, and was stolen 3 years prior. The owner only asked one question about us, wanting to know if Buffy was going to a good home. The vet explained he knew us, and relayed the story of my girl, the finding of Buffy, the bath, and vet visit. They agreed that Buffy was in a good place, and we had a new family member! Buffy stayed with us for 10 years, every day, hanging with us, going camping, travelling, and in general, being a friend when sometimes there were no other friends. She was the best dog.. ever, for us. We finally had her put to rest when she could no longer walk well, had virtually no teeth left, and was in pain. Hard? Yes very hard. Buffy cannot be replaced, and we miss her every day.
