How can I tell how big my puppy will be when she's fully grown?

Right now she's 4 months old and 11 pounds. She looks mostly border collie but she's a rescue so we don't know what else is in her.

Right now she's 4 months old and 11 pounds. She looks mostly border collie but she's a rescue so we don't know what else is in her.

I want to know so I can buy a kennel that's the right size. Of course we will love her no matter what size she gets to be.

Answer 1

Adult border collies average 35-40 lbs...the bigger her paws, the bigger the dog.

Answer 2

well there is no real way to know exactly, but if you look at her paws and legs you can get an idea of how big she'll get by the size of her feet.

I have a 5 month old border collie right now and he weighs 30 lbs and his feet are huge. They say that males are usually about 5 to 10 pounds more than females typically, but that's if they are full blooded. Females get to about 45 to 55 and males get to
about 50 to 60. But there is no real way to tell if its a mix.

Get a pen that is about 26" wide and 39" deep, that's what we got for Bailey and I think its going to be just right when he's done growing. It will probably be a little too big, but better alittle big than too small.

Answer 3

She may not get much bigger. Usually they will get as big as they will get up to 6 months of age. If she is only 11 pounds right now at 4 months she may only get up to 15 - 18 pounds and not grow no more. Check with your vet and see what he/she will say. I just bought a cocker spaniel and at 6 months old she weighed 18 pounds and has not gotten any bigger and has stayed the say size. I also have a mini doxie and she is 5 months old and weights 5 pounds and she will not get much bigger then this. I hope this helps.

Answer 4

if she's mostly border collie she should be around that size, unless she's crossed with great dane like my friends dog. The size of paws and legs should be a good way to tell. If the paws are massive, then the dog is likely to be farely large too!

Answer 5

It is really almost impossible to tell since she is a mixed breed and you know nothing about her parents. Even if you did know both her parents, she could show most of the characteristics of a grandparent or great grandparent. If she is 11 pounds now she will get quite a bit bigger since she will continue growing for at least a year. It's not likely that she will be a really big dog though.

Just accept her as she is. No matter what her size, it will happen gradually and you will adjust to it.

Answer 6

With muts it's hard to tell. A lot of fairly small dog look like collies. In general look at the feet. Big feet means a big dog.

Answer 7

Multiply the girth of the puppy around it's belly, by the length from between its shoulder blades to its tail and divide that number by the length of it's front legs from the ground to the shoulder blades and then multiply that by I ain't got a clue and you'll be as accurate as anyone else here offering suggestions.

Answer 8

She will likely double her size. You can look at the joints on her front legs, too. If they are disproportionately large compared to her legs, she will be big. But, considering her size now, I don't think she will be more than 30 pounds.

Answer 9

look at a dog similar to a border collie or that dog, more than likely your puppy will be 10lbs give or take from a similar bred.

Answer 10

the best way to tell is to look at the size of his or her paws.
