My best dog is fixed. She prolapsed when she had her first litter of pups at 3 years old. It did'nt affect her at all but she was a grown dog with alot of hunting and hogs under her belt. I've seen others that were fixed and they hunted good but I have seen a couple that it changed. Me personally, I would'nt do it unless I just had to for medical reasons or unless she was a dog that I knew I would never want to breed. What's a couple of weeks. Leave her at the house and just hunt behind your buddies dogs. You don't have to have a dog in the pack to have a good time. It would really suck if in 2 or 3 years she was the best dog in your part of the country and all you could do is remember the day you had her spayed and say that you wish she could have some pups. JMO.
But id go with this. I wish i had some pups out of her.
