I have had Toy Poodles since the 70's and have only been without them for a couple of years now. I've seen a bitch actively egging a male on to remove her knickers (little slut) so you do need eyes in the back of your head. However, if you don't have other dogs, I see no reason to bother with them. Toys don't make the same mess that larger breeds do. And can easily be confined to your garden instead of risking walking her outside. They don't get as stir crazy as the large breeds. Do, however, be aware that, to be 100% safe, you need to allow 4 weeks of caution. I had a bitch mated on day 28. The vet said she couldn't possibly be pregnant, so wouldn't need the jab. Yeah, right! She was pregnant.
I lost my last bitch a couple of years ago, she never had a litter, but wasn't spayed until she was 5 years old. I honestly recommend that having them spayed later is the way to go for me. There is research suggesting that oestrogen is linked to longevity. I lost my girl shortly before her 17th birthday, so feel there has to be some truth in this.
