shes still growing and she needs those hormones and if you are carefull there is no reason for her to get pregnant
Joly is right, I would never get a bitch spayed before her first season, her body hasn't matured properly and only by letting her go through to after her first season, can her body mature the way it that it is natural. Small dogs usually mature earlier than big dogs. I have permission from the rescue I got Tilly from to wait until her first season before spaying her, but that is because all my dogs are neutered and I have done this before with another rescue.
Hi this is just a rough translation of something that someone has posted on another forum....
Dobermann, Rottweiler, Old English Sheepdog, English Springer Spaniel, Weimaraner, Rough Collie, Irish Setter are recommended to spay after first season as they can suffer from problems with their 'waterworks' if done before....
Most of these breeds it is recommended that they wait until they are 2 years old before neutering either male or female.
It doesn't matter if they are spayed before or after their first season for it to upset their waterworks. The only bitch I have had that was spayed before her first season by the rescue, is the only one not to have waterworks problems. It is very easy to stop the leaking if you take your dog to the vet, Gracie is on Proplin for this but she came with waterworks problems.
Speak to your vet about having her spayed, they leave it to about 12 weeks after their season so that her hormones are quite, dogs that are spayed when in season, or close to it, or have an abortion, quite often their hormones stay high for the rest of their lives, I know several like this.
