I am an experienced dog-sitter and overall dog lover! From small to the extra large I have patience (and room) for all dogs.
I live in a house with a courtyard but no backyard so would guarantee one long walk a day, as well as 2x short walks to the park directly opposite my house for potty breaks. If your dog is an indoor dog, they are welcome to sleep inside, if they are more of the outdoorsy type I have a closed courtyard to accommodate your pal.
I also have experience with reptile critters should that need arise :)
