So I understand a new environment for your pet might be a little overwhelming. I like to keep the initial introduction calming and bring your pets toys or dog bed into the new environment to let him/her feel safe. I do have other dogs but I have the ability to keep them separate if your pet doesn’t like other animals. My dogs have been vaccinated. I have a large back yard where your pet can let a lot of energy out and have a ton of fun! If I would house sit I would love an introduction. Usually a treat or two helps them feel calm around me. If you just wanted a walking service for your pet I would find a route near your neighborhood or apartment complex. I make sure to stay off the asphalt as much as possible. And in the summer I bring an extra water bottle with me in case they get tired.
