I had a border collie for 12 years but two months ago, he died of cancer. it came really suddenly. We didn't even know it was happening. One morning he was happy and playful, and the next, he couldn't get up. We put him to sleep one week before my birthday. But a couple days ago, we discovered this perfect dog and we adopted him. He's a Springer spaniel and golden retriever mix. hes the most perfect puppy i've ever had.
