Hi everyone, I am am experienced dog owner of more than 40 years, and am looking to buy a whippet puppy at the end of the summer. 
I am offering a loving, adult (me) only home, with 2 huge parks within walking distance, I also have a medium sized dog safe, lawned garden for early morning and late night toilet going.I only work 9 hours per week, so am home the rest of the time.
My vet is superb - I've used the practice for the last 45 years.
I live in Cambridge and wouldn't really want to have to drive more than a 200 mile round trip.
I am more than happy to provide any more details that you would like to know about my life.

What you have written is exactly what a breeder would like to hear, so I would suggest you might also try the whippet breed clubs, most will have a breeder list or puppy co-ordinator/secretary aware of litters planned or on the ground.

Breeders that are members of their breed associations are the kind that are serious about their breed and most likely to breed with research, health testing, and the breed as a whole in mind.
