I was a veterinary nurse for 12 years it is only ignorant uneducated people whom don't have their pets neutered. believe me I know I have seen it all....you can be laughing one minute crying the next.

Fine if you want to breed from them but have a good vet maybe insurance incase of a c-section unless you super rich and don't mind shelling out the odd euro600/700.

But ultimately you are responsible for your pet.
