I have a young Beagle dog that has an appointment to get spayed the 18th, but with what I have heard, I'm wondering whether I should have it done now or not. I've been reading some different things online, and so far I've read several negative things. http://www.naiaonline.org/pdfs/LongTermHealthEffectsOfSpayNeuterInDogs.pdf One thing that I am worried about is age. On the website from the link above, it says that females under a year old have a higher risk of bone cancer...even though my dog isn't a large breed as mentioned. I am also worried about weight. I've been told that females tend to gain weight if spayed before they come in heat at least once. Is this true for any of your pets? It may just be coincidence, but my other dog was spayed before she came in heat, and as active as she is, she is still a bit chunky. She is active, healthy, doesn't over-eat, and is even on 'weight management' food. So in your opinion should I be concerned and wait, or go ahead with the surgery? Thanks.
