I currently live with a rescued Jack Russell/Chihuahua mix with some pretty serious anxiety. I've run the gauntlet of dog issues: bites, accidents in the house, dog-to-dog aggression, and pups with plenty of energy to burn. I grew up with cats as well and love them (almost) as much as their canine counterparts. I'm used to walking two dogs simultaneously and have never run into any type of issue while on a walk, and have casually provided in-home care for friends' and family's pets in the past. I've provided care for dogs and cats of a variety of ages/sizes, so I don't really have any preferences with regard to that.
