I have such a heart for animals, I spoil all of my pets with love and attention and would do the same for any dogs or cats I got the opportunity to look after! I've never met an animal I didn't love and have quite a bit of patience for those who may have more anxiety issues and need a little bit of TLC. Its always hard to leave your pets, but I'd make sure to treat them like my very own and give them lots of affection and cuddles! I just bought a house with a fenced in backyard specifically for our dogs to play in. When dog-sitting I'd rotate the times your dog and my dogs used the backyard, I know not all dogs enjoy the company of other animals. We have a mother-in-law suite devoted to this so they'd have a space to themselves!
