I grew up on 4 acres and still live there. I grew up handling not only dogs but cats, chickens, pigs, hefers and steers, so size does not scare me away! I've had dogs from chihuahas to mastiff/ pit mixes and a lot in between! I've never met a dog I didn't naturally get along with and love taking mine for walks and play time. I used to be CPR certified but with school never renewed it but I still know my training. I have a presents that most dogs are drawn too and I am very active so if your dog wants to run, I can run. If you've got an older dog and they want to have a soft slow walk, that's what I'll do!
