Yesterday, I asked on one of the forums the exact same question. Replies were that the most important thing during heat is preventing all the male dogs in the neighborhood from getting to her, unless you want your girl to get pregnant. My concern was also at first about bleeding, that wasn't as important as the fact that I need to protect her whenever she goes into heat so that she doesn't end up with mixes. If I ever in the future decide to ever breed my chocolate lab, I will do so only with another lab so that the pups will be purebred and not mixes. My puppy is 20 weeks old now, and I know that she can go into heat anytime in the next month or so.
Not sure if your dog is registered with either the AKC or CKC but dogs aren't purebreds unless they are registered as well your dog and the stud you choose should be proven in conformation as well pass all the appropriate health tests for your breed.
Those of you who have unfixed dogs should be concerned with proper and ethical breeding. We already have shelters full of mixes and purebreds. Mixes aren't the only dogs abandoned.
My GSD is AKC Registered and is in perfect health. I also have a 6 foot fence and a male GSD who is fixed. I can assure anyone that the male dog will not let any other male dog near his female. We plan on breeding her with one of our police officers akc registered GSD, because Greta probably should have been a police dog, she can spring like a kangaroo. Can catch anything, would love to attack somthing if allowed.
We only plan on breeding her once. Then she will be fixed. She's only one at this time. We need to wait one more year. Greta is a silver sable GSD and has the most beautiful white and pale markings on her chest.
I appreciate the concern. We are very responsible pet owners and treat our dogs very wonderfully. They also get 2 mile walks each day out of our fenced in yard.
The mention of breeding seems to get some feathers ruffled around here, not all pet owners who plan on breeding their dogs are irresponsible or in it for the money.
With that said.
Aziablue, If your female is in heat I would reconsider walking her outside of the yard until she is finished. They send out a scent attracting every male around and even if your male is with you and he protects his girl, I would not want to deal with a possible fight between two males or possible fighting off multiple males from my female.
