I agree with an earlier poster. Neuticals do not promote neutering, if you need your dog to have them then you are insecure. Neutering early decreases the chance of cancer and most older unaltered dogs end up getting such a large prostate that they can't pee or poop well.
As for these things to fix ear croppings...good luck finding a quality vet who will do it anymore. The AVMA now has recommended that veterinarians no longer perform this service as it not necessary. Frankly anesthesia should never be taken lightly and sometimes these can take multiple surgeries. There can be a lot of complications as well and if done wrong the dog can actually lose it's ears. Why put a dog through the pain and rish of surgery if it is not necessary?
Neuticals are a big joke in the veterinary world. Personally, one of the things that gross me out are big, old, saggy dog balls. Get over it, dogs don't need balls and they most certainly don't need their ears cut so that they look a certain way. Personally I prefer my boxers, schnauzers, great danes, and dobies with floppy ears as they are cuter and happier. It's on the way out, good luck holding on.
