JUst wanted to tell you all how happy iam with my situation. THeres alot of problems on here and its nice to read some good happy posts.
You should see the dad of my 2 litters of pups. Hes loves them to bits. he lays while they crawl on him chew him. Hes a big dog and so gentle round them. He walks carefully taking great care not to hurt them as he is usually a clumsy dog.
everyone asks me do you think he knows hes their dad. Is this possible.

Dogs are usually kind to puppies when they are not actually afraid of them.  The bitch is generally the one to have something to say about the dog being around. 
You were extremely fortunate to have bought in a dog suitable as a mate for both your bitches weren't you?  I see in your other posts one bitch is 8 years old, I presume you realised you had to seek permision from the KC before the mating in order to register them.
