haha yea whoever said breed like rabbits didnt know the truth! Its much harder than people think.
I just had to breed a doe today and had this problem. My tans are notorious for being lazy and not lifting. Are you trying this in a cage? Some things I will do in a cage is when the doe is doing circles I will catch her when her head is in a corner and will gently cover her eyes with my hand. Then I will take my opposite hand and lift hear rear end. This is hard to explain so you might have to figure a way out to do it but the most important thing is that her tail is up. If her tail isnt up then you wont be doing any good. Sometimes instead of lifting I will just hold her tail up. This doesnt always work because then she will tuck her backend.
If you dont want to go through these troubles some people will put them on a grooming table or something and try to breed them there. If its not going well enough I will just take the doe away, let the buck rest, and try again later. I had to do that a couple of times today.
