I have previously housesat for a friend while, she was away on holiday. Also used to take that same friends previous dog walking quite a bit and did some training at the same time with the dog to keep the dog's mind sharp. My friend would give me a good reference.
Used to take another friends dog for walks too. That friend I consider family now.

If I do eventually want to pet sit at my place they would have to be cat friendly and vaccinated and neutered. As my cat is a neutered male of now 6 years old.

I would like to earn a bit more money and make some more friends. 

Since the age of 5, I have had 7 dogs and I'm on my 6th cat, had about 6 Budgies, 3 rabbits and a guinea pig for pets of my own. My last dog was ex SPCA and, he used to steal food so, I trained him to refuse food. Which stops them getting poisoned. As they'll only eat if given permission to. Have since got a partial completion in Level 1 Animal Care through correspondence.

If I do use my house it'll be just for socialised, vaccinated pets. Ones good with cats.

My favourite breed of dog is a German Shepherd (Alsatian).
This explains quite a lot about me.
