My Lhasa apso dog is female and is 1 year and 20 days old exactly but she has not gotten her first heat yet. I am worried it might cause health problems for her

She could still go into heat at any time. Some dogs go into heat later than others, although smaller breed dogs tend to go into heat by a year of age. It could also be that she has gone into heat, but it was a silent heat so you didn't notice any signs of it. I'd have her checked out by a vet to be safe. Best of luck.

Some female dogs will not even get their first heat until they are about 2 years old. So not having a second heat at this age is normal, and not associated with any illness or pathology. You should wait until the second or third heat before breeding your dog, and she should be mentally and physically mature.

She may have one heat cycle per year and probably the first one she had was showing few signs or none (it is fairly common in young females). Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

It is best to wait to breed any dog until they are 18-24 months of age. I think she is too young and you should wait. Here is more information about breeding dogs. Hope this helps. Best wishes.
