Mateo came to GRRoW from Puerto Rico on 8/18/2016. He spent his first night with a wonderful GRRoW volunteer until heading to his foster home the next day. Mateo is approximately 4 mos old. He's a very sweet puppy who is becoming more and more playful as he adjusts to his foster home and his foster siblings. So far he has met both our resident Golden's and our two resident cats. He does well with all of them. I don't think he ever had to do steps before as the first night he was here I had to carry him up and down the four steps to get on/off the deck to go potty. He quickly mastered them though and now easily goes up and down them following the big dogs. He's a young puppy and needs supervision at all times, we are crate training him and he does really well. He will be visiting the vet sometime this next week for a checkup and to schedule his neuter. More to follow as we get to know him better.
