I grew up with dogs ( German Sheppard, Rottweiler, West highland white Terrier, pug). For house sitting - I am happy with any size of the dog, or also cats. I can make sure they get their medication, play time, a lots of walking and cuddling with me. If I stay with the pet at your home, I make sure nothing changes for your pet. Walks, feeding, medicine. I know they like their routine. I love going for walks, so if dog needs extra exercise I will provide it. For boarding to my place - Cats get discount applied by me ( 20%) I can only accept smaller dogs up to 30 pounds and mainly cats. Also we have a female cat ( neutered) at my place. She is very friendly with other cats and smaller dogs. Sometimes I dog sit my friend’s great Dane - sleepover for a week, feeding, training him, going to dogs park. It depends about a dog’s need - I can spend 1 hour, 30 minutes outside each time. I partially work from home and I also drive so I can be flexible. When it comes to boarding a pet to my place, there is plenty of spare space for them to move, also living room is a third room that can be completely separated. I don't usually allow pets to sleep in the bed with me. I don't have a backyard, but it is a cozy house. I would only board one pet at the time. I have a roommate and that is only person that shares the space with me.
