Sex

Glen of Imaal Terriers generally reach sexual maturity between the ages of 6 to 12 months. This means that they become capable of reproducing and can experience their first heat cycle (in females) or exhibit mating behaviours (in males) during this time.

However, it is important to note that responsible breeding practices dictate that dogs should only be bred once they have reached full physical and mental maturity, which typically occurs around 2 years of age for Glen of Imaal Terriers.

There are potential dangers and health issues associated with breeding a puppy before it is completely grown. It is crucial to ensure that the dog's skeletal structure, hormonal balance, and overall health have fully developed before considering breeding.

Breeding a dog too early can increase the likelihood of health issues and complications during pregnancy and childbirth. Waiting until the dog has reached maturity helps ensure a higher chance of successful reproduction and healthy offspring.

They carefully consider the genetic backgrounds, temperament, and overall health of the breeding pair to minimise the risk of hereditary diseases or behavioural issues in the offspring. To make sure the breeding couple doesn't have any known genetic disorders, they also do health tests including elbow and hip exams and genetic testing
