Personally I would wait till 2 years old or 3rd heat thats what I do with my boston terriers. Make sure you have enough funds incase you need an emergency c-section or anything else that may go wrong- do all the research that goes into breeding, get a couple of books and research the crap out of it and then see if this is something you may or may not want to risk your bitch/ litter for incase something goes nasty wrong. Then if you work are you able to take the time off needed for when she starts to whelp- temp reading can give you an idea on that one- but its not always 63 days from the time they are mated so can you give a phone call in and afford missing so many days- You also want to be there to watch them for the first week or so to make sure all are eating fine, weighing each pup, mom not sitting on pups, mum cleaning pups fine ect ect. Books can only tell you so much but experiencing all that may go wrong is the scariest of all.
Then do you have a suitable male and has he been used before, if so has he been tested for STD's? Yup dogs to can get sexually transmitted diseases and then you just ruined your bitch :(
Iam not going to tell you you should or you shouldn't because people are going to do what they want anyhow- but definately do the research and if its just to keep a pup from a litter then yes I will say save your money leave it to the professionals and buy one from a reputable breeder instead cause you will save alot more then you ever would breeding- since you can lose her in the long run with that said is it worth it? I know pugs are knowing for sections due to bitches narrow pelvic and pups big heads. Also is she tested to ensure you will not be passing any herditary/genetic problems onto the puppies? studd also needs the same tests.
