I have a mini daschund female, she's 9 weeks old and she humps on my house shoe( a tiger). I think it's too soon for her to be going into heat! When does these dogs go into heat ( 4 months, 6 months, 8mths?) and how will I know that it's about to happen or happening? Then What do I do? This is my first dog and I need a little help. Thanks! :confused:
