I had a Labrador for 12 years and I used to do everything for it (feed, walk, trainning).
I also use to dogsitting my friend dog. I really love dogs and all animals in general.
I will be home with your dog all day to play with it, go to the park and to walk with it.
I have no other animal in my place so my attention will be on your dog and it's secure environment for it.
