We have a 35 lb beagle , George, who is very submissive and gets along with all dogs. Our previous dog was a yellow lab who lived to the ripe old age of 15. George is getting old so is much less rambunctious these days. We have a single floor in our 1200 sq ft apartment with a very large deck extending out the back over the two-car garage. In the warmer months, the dogs can go in and out at will. We are a long time married couple who love dogs. We would be happy to share that love with your pets. We are also within walking distance of a doggy park to give the animals more chance to exercise.
