As someone who's spent most of his life around nature and animals, caring for pets comes naturally to me. I work for the Wildlife Trusts and it runs in the family, as my mum's a wildlife photographer and my sister’s a marine biologist! I've had dogs, cats, fish, and even rabbits once upon a time. Am comfortable around any pet, and I'm even happy for example to feed any reptiles or invertebrates you may have as well. Our pets are part of the family and often our pride and joy, so having that knowledge that they're well-looked after is equally priceless. As an accountable person I would always answer your calls/messages promptly while caring for your animals, and provide regular updates if that would give you peace of mind as well. Walks could be brisk as I like to think I'm in good shape, so could take your dog on a decent route (if I'm unfamiliar with your area and you have any in mind I'm open to suggestions!).
