Absolutely love dogs. My Sam is very spoilt and we have a minimum of two walks a day and he is an inside/outside pet...
I work 6-2.30pm Mon-Thurs and 6-11.30am Fridays.
Sam is well behaved and gets on with most dogs, though he prefers female dogs. Loves cats but hasn't lived with one yet, however I know he'd love a kitten, which is why I don't offer adult cat services at this time. Definitely prefer meeting first before proceeding to ensure everyone fits, as I want everyone to have fun and be happy (both your pet and mine).
I would also respect your home while petsitting (if you choose that option) as we would expect the same if someone stayed at ours. I believe pets can definitely handle you being away better, if they're in their own environment, but we'll certainly give them a wonderful experience if they come hang out with us.
