Birth – 2 Weeks

During this stage, the puppy’s eyes and ears are not developed but their sense of taste and touch are developed.

They cannot see or hear, and they depend on the mother for warmth as they cannot regulate their body temperature. Towards the end of the second week, the legs grow stronger, and their weight doubles.

3 Weeks – 12 Weeks

During this period, the puppy undergoes a lot of growth changes. Their teeth start growing, they start seeing clearly, and they can begin socializing.

Weaning also happens in this period and they can move to their new homes at around 8 weeks of age. You can start house training when they are 12 weeks old.

How Big Do Mini Australian Shepherds Get?

The best way of knowing how big your Mini Australian Shepherd will be as an adult, look at their parents.

The size of the parents is a clear indication of how your puppy will be when they are grown because of the genetic transfer of physical characteristics.

If you do not have access to the parents, then doing a DNA test will help.

Another way of knowing the adult size of your Mini Aussie puppy is to check the paws. If they are unusually large, then they are still growing and will fill up their frame so that the body is proportional to the paws.

The height of a female Mini Australian Shepherd is between 12 and 16 inches and the weight is between 20 and 40 pounds.

On the other hand, a male Mini Australian Shepherd is slightly larger with a weight of between 30 and 50 pounds and a height of between 14 and 28 inches.

Will Neutering/Spaying My Mini Australian Shepherd Affect His Growth?

Spaying and neutering are surgical procedures meant to remove the reproductive organs of dogs.

Spaying your female Mini Australian Shepherd means that their ovaries are removed while neutering is for male Mini Aussies where their testicles are removed.

Spaying and neutering should be done at the right time otherwise the growth of your puppy can be affected as growth hormones are linked to reproductive hormones.

So, if it is done too early, your dog may grow taller than average as the growth plates may not close. Spaying and neutering help with reducing aggression and preventing breeding.

Typically, female Mini Aussies should be spayed before their first heat while male Mini Aussies need to be neutered when they reach puberty.

Therefore, the right time to neuter or spay your dog is between the ages of four and nine months, but you should consult with your vet to know exactly when to do these procedures.

How Much to Feed a Growing Mini Australian Shepherd Puppy?

Using a Mini Australian Shepherd feeding chart will help you find the right amount of food to feed your puppy.

When puppies are under four months old, they need three times their RER and between the ages of 5 and 12 months, they need twice their RER. The amount reduces as they grow older since their energy levels reduce.

RER = (weight in kg)3/4 multiplied by 70.

When Mini Aussies are three months old, they eat between 2/3 to 2 cups of food, three times a day.

When they reach five months, they eat between 1¾ to 3 1/3 cups of food, and the amount reduces between the ages of 6 and 8 months.
