I have my second big dog at home and I have raised them both from puppy hood to city traffic training. Now again in Texas, I do dog walks for small and medium size dogs in their own neighborhood. You may know better, what streets are good and shaded, when summer time is hottest. I do collect after dog as I do after my own dog, while I travel. I have a car and I can take dog to car drive if needed. Even I have fenced yard, for now I am not taking any dogs to my home because my own dog get very excited about visitors and its better he goes visiting others home, while I am gone, he gets along if there is no guarding needs to be done same time.
