My dog and another used to cycle within a week of each other

Customer Question

my dog and another used to cycle within a week of each other for the last 5years.wen the dog moved away she hasn't had a cycle since, she's missed 3 cycles. and should be having one about now and isnt. she's a west highland terrier born 4-5-10 . is something wrong or is she old enough where she'd stop on her own .
we were looking at breeding her this year but w/o a menstrual cycle happening I don't know if it's possible at all.
the loss of her friend I figured could be a factor but I'd thought her system would kick in again on its own .should I have her seen, is there a potential health issue.

As dogs get older it is possible for their heat cycles to become irregular and even stop all together. HOwever, 6 years old is not that old really. Dogs can also have silent heat cycles. With a silent heat cycle the dog is going into heat but the outward signs are not evident. I've found many females in a silent heat are still more affectionate than normal and an experienced stud still can sense they are in heat.

Now dogs can have a variety of heat issues including prolonged heat, a shortened heat or a split heat. Read about these here:

And there are medical causes for a heat cycle to not occur such as hypothyroidism. Often a thyroid condition will affect the heat cycle. So it would be a good idea to have your vet take a look at her. In addition, be sure your vet gives the ok to breed. If she has never breed before, 6 years old may be a little late to start. She might have a more difficult time at delivery than a younger dog.

Hi Lora,

I'm just following up on our conversation about Harley Dot. How is everything going?
