Me and my mother used to foster puppies from the local shelter. I have owned just about every size dog, my mother has two Newfoundland, Bernease mountain dog mixes so I'm very fimiliar with giant dogs as well. I work early morning on weekdays but for the most part I am available pretty much all day and of course the weekends. I'm very patient so if you have a dog that likes to play fitch for three hours as long as my arm doesn't fall off I am fine with playing until they are tired. I love exercising so don't worry they will get their exercise in too. I believe animals are they greatest blessing on this earth and I will treat them as such. Animals are just kind souls who need some play time and love.
