I have grown up with dogs as small as 30 pounds and as large as 140 pounds. I personally do not have a dog at this time, but I am most familiar with the terrier breed. I grew up with an Airedale and a Black Russian terrier. However I house/dog sit for multiple dog breeds ranging from Hounds, Golden Retrievers, Boxers, Rottweilers, and German Short Haired Pointers just to name a few. I’ve watched just 1 dog with 3 cats and 3 chinchillas at a time, to up to 6 dogs at one time. I will walk your dog or dogs and also play fetch with them. If they’re scared of thunder, I have plenty of strong cuddles and kisses to calm them. No dog is too small or too big for me to handle!
