My female labrador dogs sexual behaver.

Question
I think my lab is about 6 or 7 months old and we have no other dogs (but we have 3 cats) and ever since we got her we bought her a bed and for some odd reason she just goes and humps it O_o so can you just tell me if this is normal because it cant be dominating.

Answer
5 months old is usually the time when puppies become sexual reproductive. She's basically going through puberty. I would recommend getting her spayed. And if you don't get her spayed, it can harm her health and males can smell her from over a mile away when she goes into heat/ starts bleeding. Males do all they can to get into your yard. If she gets pregnate, she coud die. She is way too young to have pups. PLEASE be a responsible pet owner and get her spayed! Thank you!
