Never, but if they are past there prime they may act a bit wierd after.
at least 1 year on dog yrs i think
he should get fixed
His testicles are removed surgically.
It shouldn't maybe you should call your vet.
Yes as long as the male dog is not fixed
If your male dog is not already neutered, neuter him.
Yes. It definitely happened to my dog.
The female should be spayed (fixed) at about 6 months. Some believe that she should have a litter before being spayed, but the only thing that does is add more unwanted dogs to the dog pound.
they could but they wouldnt do it
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
the male dog acts funny because they know they can not "make anything" with the female dog.
If you have a female dog that's not fixed, then you will run into this problem. For the male dog will want to "reproduce" to make the new puppy generation. If you want to have pups, then this is fine, if you don't, then I suggest you try to get your dog fixed.
Yes My dog Peter has locked with my female do numerous times. My female dog also was not in heat at the time. It is actually a regular occurance in my household and my male dog has been fixed for 2 years now.
