I have had dogs in my life for 17 years, so I have plenty of experiences with toy to full sized dogs. If your dog is staying over for the first time, provide a toy or article of clothing as it will help soothe any anxiety. I have a 7 month pup that is 10 pounds, he has been fully socialized and loves to play. We usually hike in Great Falls and Bull Run Regional Park. Please provide instructions on if your dog is anxious with the car and I will stay local. Let me know about any food allergies for your dogs as this is a treat happy household. I am active duty military so I am looking to care for pups over the weekend. Please contact me if you have any questions!
