maybe it's still not in the state of heat.
wait for it to menstruate then count 11 days then it ready.
No they can be introduced while in heat.
If the dog is a male, no. He will be inexperienced and his sperm may not make a female as fertile as a younger dog and a female is a definite NO. A female should only be bred on her 3-5 season. If she has never bred after that time she should't mate at all as she may not be as good a mother as a younger one.
Any female dog that has had a litter (no matter if it's a pure bred dog or a mixed breed) should have a good physical by their vet. Just as women do after giving birth. It's important the female dog has nutrients to give the pups when they are nursing.
The breed, Bernese Mountain Dog, was not bred to be small. Why do you want a small one? Obviously you don't want this particular breed then. Find yourself a small dog that you do like. If you want this breed then you have to like the entire breed as it was meant & bred to be. This is a working breed & not bred to be small or it could not function.
A female pug with a hernia SHOULD NOT BE BRED even if repaired. A male dog with a hernia may be bred. You can have the hernia repaired surgically.
nothing, don't become a byb spay your dog.!
Not unless you want inferior, probably deformed puppies.
Selective breeding is where, say you want a really spotty dog, you would breed a female dog with lots of spots with a male dog with lots of spots. Their offspring would have more spots than a normal dog of that breed, then the offspring with the most spots are bred together. This carries on until you get a dog with the right amount of spots that you want.
you should get a female if you want it to have puppies or you should get a male if you want to play with your dog all the time i have a male dog
Better than 90%. Honestly.
A labradoodle is not a pure bred because it is a mixed breed. If you want a "pure bred" labradoodle, make sure its parents are a poodle and a labrador.
