Breeding English bull terriers requires bringing together a fertile male and a female in heat and letting them mate. Setting up a mating session, caring for the dam during pregnancy and taking care of the puppies upon birth takes at least two to three months.
- Choose a male and female English bull terrier
Select a sire (male) and dam (female) that are registered with the American Kennel Club. The sire can belong to another owner. Find a sire that is a good genetic match for the dam that balances out her negative qualities. The sire must be between 7 months and 12 years of age. The dam must be between 8 months and 12 years of age.
- Mate the dogs
Prepare for mating by having both dogs checked out by a veterinarian. When the dam is in heat, take her to the an environment where the sire is comfortable. Let the dogs mate. A handler may be required, or artificial insemination. Do not breed a dam during her first heat, as it is unsafe.
- Take care of the dam during pregnancy
The dam's pregnancy lasts about 63 days. The dam gradually eats more. A veterinarian can confirm pregnancy at 28 days. Set up a whelping box for the dam to give birth. The birthing process is simple and does not require much assistance. However, be prepared to call the veterinarian in case of emergency.
