16 month old Yorkie still has not had heat
 
Hi,
I own a 16 month old Yorkie and she has not come into heat yet. The vet seems to think that she is just a late bloomer. She is almost 5 lbs and has a slender body, does her size have anything to do with it? Has anyone ever experienced this?
Thanks in advance,
Tia

This isn't uncommon at all! My breeder had a bitch that didn't go in to heat until she was 20 months!

Just curious, what kind of food are you feeding her?

My Yorkie is almost 12 months and just started her first heat. Anyone have information to help with the decision of breeding her one time? A little nervous about it so want to be sure.

She is still too young. How much does she weigh? You have plenty of time to research breeding and get her checked out before you make that decision. It is recommended to breed females on the second heat or when they are at least 18 months old.

Here's another factor to consider. She may have had a silent heat and you didn't catch it.

How much sun does she get. That is also a contributing factor.

Very few dogs have there first heat after a year and half but since the first heat is often a silent one, many time it goes unnoticed ...that all.

And good call for the Sun comment, you right on that one too. :thumbup:

Just curious, how does that factor in? Mine girls are strictly house dogs and they have very regular heats. Of course they get sunshine through the windows but they don't go outside.

YorkieLover30's dog is having her first heat at 12 months so I doubt she had a silent heat prior to that. Most of my females have come in heat around 8 to 10 months for their first heat.

Sun is a source of vitamin D and has very much to do with hormones.....it also, is a factor in the boys being sexually potent. I learned this through canine reproduction seminars and through my reproduction vet. Most animals, human and otherwise require sunshine...

It wasn't my intention to direct the post to you just adding on to yours.....and directed it at the OP

I also have study canine reproduction at school and second that comment. If a female is keep in the basement all the time, she might even start skipping heat eventually.

You will get some vitamin D even if the sun have to go through the window.

There is no life.. without sun.

And Fresh Air.

In addition boys sperm count will weaken if not getting enough sun. Rendering him unable to inpregnate a female...not meaning he can't do the deed, just not father a litter.

You shouldn't breed a yorkie till she is 2 years old anyway just give her time. She is fine. Make sure your feeding her good quality food maybe give her some vitamin supplements in her food too:).

The recommendation is 18 months or 2nd heat cycle. However, there is the maturity factor that fits into the equation too. If the female is not mature enough one may want to wait until the 3rd heat cycle.....
