Spaying...what do you think?

My old Dixie female always had irregular heats. By the time I got a good heat (fall of the year) and tried to breed her, she didn't take. Took her to the vet and she had a grapefruit sized tumor in her uterous that was growing....not sure how long it had been there but it had spread and the vet had to cut so much out of her , he didn't think she would survive the surgery but she did.

You may want to get your female x-rayed and make sure she doesn't have something like that causes the odd heats.

Dixie got fat after I had her spayed, but thats because I quit hunting her, not because of her being spayed!
