Question
My little Sheeba is almost one year old and hasn't gone into heat yet, to the best of my knowledge there was no obvious blood or swelling. Is she just a late bloomer or is there a problem. I have never owned a boxer before. And I would like to breed her eventually because she is so gorgeous :) so I really hope there is nothing wrong!

Answer
Age can vary and is inherited genetics. They can have heats as early as 4 months old, but rare, and as late as 2 years old.

Also, thyroid conditions can cause delay, cessation, and miscarriages.

Have your vet check her for thyroid problems.

Does she shed a lot? Does she eat good but ribs show?

A simple blood test will check thyroid.
