I owned a flat coated retriever/border collie mix for 15 years so I have no problem with high energy dogs or older more fragile pups. I have also been dog sitting dogs of all sizes and ages for 10 years. This includes diabetic dogs so therefore I am able to administer insulin shots, and older dogs that require oral medications and other needs. I have also walked dogs of all sizes and am comfortable with all breeds! In addition, I am an avid hiker and runner so if your dog needs rigorous activities I have no problem accommodating their routines. Finally, I graduated with an animal science degree so I'm completely confident I can care for your dog and ensure they have the most fun!
