Sheepadoodle Growth Chart

Birth to 2 Weeks

Between birth and 2 weeks of age, Sheepadoodles are deaf and blind. They are unable to look after themselves and are fully dependant on their mothers as the only senses they have are taste and touch. Sheepadoodles spend majority of these 2 weeks sleeping and nestling as close to their mother as they can. Their muscles are not developed and they cannot walk.

3 Weeks to 12 Weeks

From 3 weeks to 3 months of age, Sheepadoodles start to become more independent. At the beginning of this period they will get their hearing and sense of smell. Their eyes and ears open so they become much more inquisitive about the world. They start to interact with litter mates, bark and walk a little as their muscles start to get stronger.

Sheepadoodles start to become more aware of their surroundings and start to interact with others. Weaning begins during this stage so they start eating food other than their mother’s milk. By 8 weeks, they have full use of their senses and usually go to their new home.

4 Months to 6 Months

Teething begins between 4 and 6 months of age. Many Sheeapdoodles undergo a big growth spurt at this age as they are only eating puppy food now. At this age, your Sheepadoodle will be at least half their adult weight.

7 Months to 9 Months

Most Sheepadoodle reach sexual maturity between 8 and 12 months of age, except for Standard Sheepadoodles that may reach sexual maturity slightly later. Female Sheepadoodles go through their first heat if they are not desexed.

10 Months to 12 Months

Most sizes of Sheepadoodle are fully grown or nearly fully grown by 12 months of age with the exception of Standard Sheepadoodles that can keep growing until 16 months of age. Sheepadoodles get their adult coat and you’ll eventually have to swap the over to adult food. At this age Sheepadoodles are extremely active and also very inquisitive. They love exploring their world and learning new things.

Unfortunately, this is the age where you might start having problems with your Sheepadoodle as it is the adolescent stage. Sheepadoodles may start displaying some regressive behavior like not listening to your training commands, being a bit aggressive or chewing up stuff. This is especially the case if your Sheepadoodle is not desexed as their hormones will start to kick in. Just remember that this won’t last long and be patient as your Sheepadoodle is a teenager.
