Toy Yorkie in heat

Question
How long does a toy yorkie stay in heat. What age should you breed a toy yorkie. I have a toy yorkie and she is in heat and she is only 6 months

Answer
Connie,

First, a toy Yorkie should never be bred.  Any Yorkie that is 4 pounds or less should not be bred because they are too small to safely breed.  The heat cycle lasts for three weeks and after the first few heats she will establish a regular pattern of going into heat.  However, if your reference to a toy does mean it is 4 pounds or less you really should have her fixed.
