How Big Should A Aussie Be

by Michel
(Spokane, Wa)

We have a Aussie, named Auzza and she is going to be 9 months on August 16. We bought her from a breeder here locally, but had no papers. I personally saw her mom, and she was a full Aussie, but I didn't get to see the dad because he lived else where. My question is, how long does it take for Aussies to be full grown? Auzza, is still really small, she is a female and I know they are smaller than males. Her mom was a lot bigger than what she is. How much should they weigh full grown as well? I am not sure how much she weighs but she goes right below my knee. I am beginning to think we ... have a Mini.

I have a female mini-Aussie. She is 17" at the shoulder and weighs 30 lbs. I also have a female toy Aussie. She is 13" at the shoulder and weighs 20 lbs ( we have been working for a year to get her weight down!)

An Aussie's size

There is really no way to tell how big she will be. Depends on genetics and the parents. Unfortunately you only got to see one parent and
you don't have any pedigree paperwork to do a little research. Did the person who bred this litter give you any information as to why they didn't get the puppies registered? Aussies are not full grown until they are 2years old. Give her time...she will fill out.
Unfortunately, you get what you pay for when you pick a puppy from someone who does breeding for fun.
I hope that helps.

I have a 7 month old male who has been 60lbs for the past month so maybe you do have a mini.

Don't worry!!

I have a 6 1/2 month old Aussie that is only 38 lbs and stands about 18 inches at the shoulder. She is a standard Aussie, not a mini. An Aussie can be anywhere from 17-26 inches in height and weigh anywhere from 40-90 lbs. That is a wide range of heights and weights and maybe your puppy, like mine, is on the smaller side of that range. When people comment on how "tiny" my pup is I just tell them that the best things come in small packages.

70 lbs is too large for an Aussie at 7 1/2 months. I would be more inclined to think he is not a full bred.
