is this a method only a vet can do?
Has anyone "helped" out there dogs in insuring there will be a litter? tips/pointers? I'm calling my vet later today to ask his opinion and advice.

my story:
my male is nearly 2 years old, the female 5. She is aggressive and is not allowing my male to mount, so we've had to hold her so he doesnt bite him. This is his first studding experience and he's got the motions right but I think he stands a little high to connect. He has ejaculated, around the area but not directly into her.... We will be trying again tonight. Help?
