Will the real owner please claim this dog....

So yesterday evening we got a phone call from the Animal Shelter.....!!! Hmmm - let's back up a bit. You need to know what happened last year in order to understand this call. ALMOST EXACTLY one year ago, we went to the animal shelter. My husband and son found a two year old, male, black Lab they really liked. They waited the required "waiting period" and went to the shelter and adopted him. He had to go to the vet and get fixed, vaccinated, and chipped....and the license. We got him supplies and brought him home. We named him Gunny. My son was in heaven. It was the first time we (our family) ever had a dog. A few days after we took him home we received a call from the shelter telling us that the owner showed up and they would like to have their dog back. There were actually two black lags (one male, one female) that came in as strays. They both got adopted out on the same day, one by us and one by a family. The small female dog was returned the next day because the family that adopted her already had a dog and it didn't get along with the female lab. Anyway, the owner was able to get her back and the Shelter was calling to get the other one back. They said legally dog is ours but they wanted to know if "we would be nice and give the dog back." We struggled with it for a while and talked about it as a family on what we should do. We debated on whether the owner was responsible enough. What happened that both this dogs got out? Apparently they were owned by some girl, and when she was at the animal shelter she was crying that they wanted her dogs. The Shelter said they wanted proof. It took them over three days to come back and show them proof. We thought, if she was so upset about losing her dogs, that when she finally found the dogs, it took her another three days to come back and show them proof!(?)!! I would have gotten on the phone with the vet and had them faxed over proof. I would have shown them photos from my cell phone....something. Also, as a responsible pet owner, she failed to get either of the dogs fixed, no tags, not chipped.... nothing! (Side note: we found out the girls name and what city she lived in. Turns out she is a porn star. Not that that should matter , even port stars can love a pet. We don't remember her name anymore.) So we thought the best thing to do would be to give him back. Even though we felt he was part of our family and we loved him. He would go back to his owner and to his sister black lab. Our son was very sad. We told him that sometimes the right thing to do is also the hard thing to do. My husband took Gunny back. Ironic side note........ turns out Gunny's real name was Gunner. How weird is that??!! Now back to that call yesterday evening. We get a call from the shelter. GUESS what responsible dog owner "lost" their dog again? GUESS which responsible dog owner did NOT change the contact information on the chip?!!! You can really tell how she wanted to make sure she was able to get her dog back if it ever went missing again. So, the call we got was from a different shelter in a different county. My husband explained to them that he was not our dog and what happened. About a half hour later they called again. They said that IF we wanted to they "would consider us the owners" if we wanted him - since we are the name on the chip as the owner. She said she would also waive a bunch of the fees and just charge us for the boarding. He is in a regular shelter (not a no-kill rescue). They also said that they are over crowded and that he would be transferred to a different shelter on Monday. We debated on getting another dog. We thought we would wait. We also pondered taking in a "Guide-Dog" puppy. About two months after giving Gunny back we were driving by the Animal Shelter and went in. There was this one dog that really loved my son. Other people would come by and look at her and go. She didn't really do anything. But, when my son walked away she would whimper. She was such a cute pup! She was about 8 months old and a pretty good size (not a small dog). They had her down as a stray that had come in the day before. They next day I went away for a business trip to New York. I wondered if after the waiting period, I would come home to a new dog in my house. And the answer to that would be "yes"! We named her Riley. She's a white dog with black spots on her coat. The black dots do not site on her coat (like a Dalmatian). She also had some really big ears - that stood up. She also smiles!! She really does have a great personality. Now the dilemma we ended up adopting a dog after we returned Gunny. How can we now take him?! My son wants him. I honestly don't know how we could do two dogs?! We also have three cats. Two years ago we didn't have anything. I take that back we had a goldfish. I really have to write a lil blog about the goldfish). The cats is another story too.....! So, did I mention that I am allergic to cats and dogs?! It triggers my allergies and then my asthma. So, GUESS where we are going today?!
