Today when I got home from school, I saw a golden retriever in the lot across the street. As soon as I got out of my car he came over to me and rolled over onto his back. Upon closer inspection, I realized that he'd obviously chewed through a wire cord that was clipped to his collar. I really dislike dogs being chained and this guy was so sweet that it just immediately broke my heart. I took him into my back yard and introduced him to my dogs who he immediately got along with then brought him inside for a bath and some food. He has no tags and I'll take him to have him scanned for a chip tmw, but honestly, I don't want to return him back to whoever was keeping him chained. He's old enough that he's starting to have some hip issues and with his amount of fur he probably shouldn't be outside in the summer here. It makes me sad and I don't want to send him back (if the owners even claim him), but I don't know what else to do with him. I already have 2 large dogs and he's not house trained. He was extremely hesitant to come into the house, so I imagine he's always been an outside dog. Sigh...what do I do?
