My dog and I are very active, we love to go for long walks, go to the dog park, or going for a hike. I live in an apartment (4th floor walk up) and although I don't have my own yard I take my dog for as many walks/runs/hikes as possible. Toby is a large dog, but he grew up with a little ten pound pup which taught him how to be around and play with small dogs. He loves all dogs and is extremely friendly. I do prefer the dogs I watch to be crate trained so that when I am at work they don't get into anything. Toby and I look forward to having your dog for a fun sleepover!
