Hi Slee,
Thanks for replying :)
No I am definately not going to mate her again,my nerves haven't even recovered from last time yet :o and I dont think I am going to breed again anyway.
As to my mums dog,no he is not a humper

,he only bothers when either my dog or my mums friends dogs are in season or about to come into season.
Callah is fine in herself,eating,drinking and playing as usual but as I said she is swelled but only very slightly .My OH says she isn't and that she just looks normal but then again he's not in the habit of making a point to look at her nether regions,as he so nicely put it.

I will keep her on her lead whilst walking just to be on the safe side and will contact our vet to make an appointment for him to just give her a good look over,but as I said she seems in pefect health.
