I plan to build trust with your friend by understanding their boundaries and wants first. Then, I slowly introduce your fur child to various forms of stimulation based on their comfort level. For cats, I typically err on the side of caution as many cats can be anxious when their owners leave. If your cat appears anxious or tense, I will give them space, slow blinks, and move closer to them as much as they feel comfortable. For dogs, I have found that taking the dog on a short walk at the beginning helps to build trust! If this is possible for your dog, we will take a short walk before returning home. If this isn't possible, I will typically use treats provided by the owner to build trust. I always look at how the dog is responding to me before engaging. If a dog looks uncomfortable or is showing signs of agitation, I give them space and let them come to me. Dogs who feel safe are happy dogs!
