toy poodle

Question
QUESTION: I have a 9mo. yr. old female poodle and she is in her first heat. I don't know if i should leaf her diaper on or how long.And our yokipoo  is peeing in the house should i put a diaper on him to.How long is her heat because i don't know when it had started can you tell from the color of it or not.
ANSWER: whether you use a diaper is up to you.  Personally I dont use them.  I certainly wouldnt leave it on her when she goes outside.  And if it gets wet and stinky then by all means take it off and wash it.  As far as your yorkipoo sounds like you need to go back to step one on potty training.  Let him know that is not acceptable with a strong NO.  Do not put a diaper on him.  Just work with retraining him.  Female are in heat for 3 weeks.  With bleeding usually only in the first week.  During any of this time she will be suceptable to males so if you dont plan on breeding her you need to watch her very carefully.  Even when she goes out side.  Once she is out of heat I would highly recommend getting her spayed.

QUESTION: I won't her to breed with my yorkipoo (freddy) shound i keep her diaper on her or not when she is inside . Because freddy is " trying too" And why wound he pee on her?

Answer
Then yes I would keep the diaper on.  However that doesnt mean that they can be left without supervision as males WILL take the diapers off.  He is marking her as his territory.  That can be normal for males.  I have a male that does it if I dont remind him not to.
