Breeding is a huge commitment - there is a lot to consider. You need to be honest with yourself. Plenty of people breed - not many are GOOD breeders, you should aim to be a good breeder and set yourself apart from others who are only breeding for cash without a care for the future of the breed.
We all think we have the world's best dogs - it's only natural but breeders need to be able to see the faults in their dogs, have a good experience support group around them to also help them see the good and bad points within their dogs temperament and structure.
Breeding isn't risk free - your bitch could die and it could change the temperament of both of your dogs. Breeding your dog has no benefits for them.
- The dogs should both be KC registered or similar - knowing their lineage is helpful in deciding your breeding plans to produce the best puppies. Helps make you aware of any health issues that could be potentially inherited but can't yet be tested for. You'll also need to work out the Inbreeding Coefficient or COI of the future puppies. Having a good relationship with your dog's breeder is very helpful since they will know their lines best and should be able to mentor you.
- Being a member of the breed club - breed clubs typically have much higher standards and ethics than a registering body like the KC. Get yourself involved with the club, attend shows, let your dog's prove that they are a great example of the breed by winning and taking part in breed and KC shows where they will be judged by someone impartial and experienced with the breed.
- Health testing - once old enough, get the recommended health tests done for the breed

If your dog does well at showing, passes the health tests, you have a good experience support network around you - then you can consider breeding
- Finding a stud - you'll likely have to outsource to find the best stud to compliment your bitch. Both structurally, temperament and health wise. It's extremely rare for a good breeder to own both the bitch and stud. If it's your bitch's first litter - ideally you'd need to find an experienced stud with an experienced owner to help during the mating to prevent either of them getting injured.
- Ensure the bitch is the correct age, she can't be too young or too old for her first litter. Have a good worming protocol in place for her pregnancy. Set up a safe den area away from busy places and other pets, including other dogs in the house for the first couple of weeks - you'll need to take time off work in order to keep an eye on them. Can you afford to do that?
- A scan to confirm the pregnancy and give an idea for the number of puppies - you'll need to have a vet on standby when she goes in to labour. What if a puppy gets stuck? How long do you leave her to push before a puppy appears before seeking vet help? Do you know how to help start a puppy breathing? Make sure you've counted all the placentas? You'll need to know this and have the answers - that's why having an experienced mentor is vital.
- Chihuahuas might need a C-section so have enough spare funds available in case an emergency C-section is needed. Can be ÂŁ2000 in an out of hours emergency. Most insurance covers don't cover breeding expenses either.
- Socialisation and habituation starts at home with the breeder - gives the pups the best start in life. Puppy culture is excellent for this -

- Before 8 weeks of age, or older with vet permission the puppies must be microchipped - they must have your details and the new owners details.
Ideally you'd have a waiting list lined up before the puppies are born with backups just in case people back out - you'd need to vet these homes to ensure they are knowledgeable people.
Then you have created these lives that you are also responsible for - keep in touch with owners, if they can't keep their dog will you take it back? If you can't, having a good experienced support network in place helps here because they'll be able to help place the dog in a new home.
Breeding done right - isn't a business. It's a passion, there is no monetary profit.
If you make profit or breed more than 3 litters a year - you'll need a license from the council -
