Pet Sitter Job in Beckenham, England

I am looking for a dog walker or dog sitter (in my home) for my lovely dog Otis. He is very friendly and loving but as a Bassett Hound can be stubborn to walk. He is not yet castrated but will be in circa 3 weeks therefore while he is not keeping him away from other males is a must as reactions on both sides can be unpredictable. I need someone who is comfortable getting to know how to walk him and being assertive. He is 25kgs and can take some warming up to walk properly with new people. He can’t be let off lead as he is a scent hound but is happy on his stretchy lead. Ideally looking for someone who is used to handling bigger breeds who may pull. He’s honestly a very lovely pup but anyone who knows Bassett hounds knows they can take some convincing!
