Friendly and confident doggy minder

I'm in my late thirties and have had dogs all my life. My family have had german shepherds, border collies, retrievers and mongrels -- all loved, all well-behaved.

I live in a semi-detached home with a garden and take my dog out for walks three times a day. This is to an enclosed, dog-friendly green space which is approximately one square mile.

My dog is seven years old. She is a border collie. She is very well socialised and friendly and confident with other dogs; she will happily play with them. She also keeps a close eye on dogs who stay with us.

I treat my dog as a family member and will extend the same courtesy to your dog; plenty of cuddle time, playtime and thrice-daily walks (modified however you wish).

I am confident with dogs large and small and have plenty of experience with the demands of puppies through to older dogs.

Sorry, but I can't mind bull terrier types. I do not believe these dogs are 'bad' (no dogs are bad) but I would need to know their owner very well before committing to caring for one. I have a duty of care to my own dog as well as yours, so I must be realistic about ensuring safety for both.
