I am very comfortable around dogs of all sizes and ages. I have a chocolate lab, Abbey, who I have trained and love walking and running with. My girlfriend has a Daniff so I am also experienced with massive dogs. As mentioned before I have raised chocolate labs allowing me to work with very young puppies. While sitting I am willing to do almost any activity that your dog enjoys such as walking, running, dog parks, or anything else you would prefer. I am available after 3 P.M. on Monday- Thursday. Fridays I am available all day and depending on the Saturday I am also available all day. I am very flexible to your dog's unique needs because each dog and situation is different and unique.
