Little female spayed - strange behaviour

[suzi-q]

Well, at the risk of sounding a bit dim, my little 9 month old terrier bitch appears to be humping things. She does it on her cushion and also tried it on our other dog (spayed male).
I guess she would have maybe been coming into season and this is her way of feeling a little frisky.
Is it normal? Hope you don't all think I'm nuts for asking this.

Hi, My JRT 18 month old bitch does it all the while, with toy's cushions and poor old 2 year old Freddie. Ithink its a dominance thing!!!!!

Chaffinch is probably right try feeding the other dog first and letting the little one know she is being fed last and therefore lower in the pecking order - it might put her in her place- but it can also be a hormone imbalance - if she was only recently spayed it will probably work out of her system soon. If it becomes a real nuisance have a word with the vet - Good luck
