So i was just wondering..what or if theres an average weight for 12 weeks?
she was at the vet for her 2nd set of shots, and the vet said shes at a normal healthy weight.. 6.5 pounds.
but we met up with her littermate the next day..who even at the time i picked maggie up at 8 weeks..was small for her age. her litter mte is 5.4 pouns right now.. thats over a pound lighter then maggie.
you could tell the size difference yesterday when we had them together..

Oh Chelsea don't get caught up in the numbers. Every dog like every child is different!!!!! If your vet said she's great on weight just roll with it. I thought Fletcher was going to be a big cavalier however now he is perfectly standard size. You never know but I sure do hope my kids are taller than me.:lpy:

Thistle was a hefty girl when I picked her up (I don't remember how much though-not fat just a lot of wiggly puppy), she was the largest in her litter at that time.

And somehow she grew up to be on the small end if the spectrum. She might weigh 14 lbs now at 2 years old.

Our first puppy (a male) was about that size but as with you our vet advised he was not overweight and he turned out perfectly healthy and a good weight. Our girl was smaller at about 5 pounds at 12 weeks - just depends on the dog, dont be worried!

I just pulled Luke's records out to check on it. He was 7.5lbs at 12 weeks. So, he was possibly on the larger side. He will be 4 next month. He was 13.5 lbs until he started flyball (at around 2.5). He's been ranging around 14-14.5 since he was 3 years old. He seems like he's right about average height, at least according to standard. He measures at 12.5 inches at the shoulder.

Lady was the smallest in her litter and i expected her to be very small. She was only about 5-6lbs around 12 weeks (3-4lbs when I got her at 8 weeks) but now shes 11 months and is just over 15lbs.

I wouldnt be concerned with her being overweight, especially being so young still. One thing to be careful of though is after spaying they can put weight on rather quickly. It almost seemed like overnight and lady had a bit too much fat on her. So just make sure that once she is spayed you cut the food down a bit and keep a close eye on her for weight gain, and to figure out the proper amount of food.

Have found a website that predicts adult weight from age and current weight for different breeds including CKCS. I was reassured that Lottie - 2.45kg at 12 weeks is reckoned to be 5.3 kg when adult which is great. It's difficult to judge because we don't know any Cavaliers her age and the pups at classes are always enormous by comparison!

I tried out Luke's 12 week weight in a calculator. It came up with 16 lb 1 oz for his adult weight. I think he'd be rather fat looking at that weight. Of course, for a larger dog, being off a pound and a half isn't much, but for a tiny guy, that's quite a bit.

It is hard to make accurate predictions with calculators - they are more for general fun than accuracy! Each puppy is so different, and the likely weight depends on factors like the size of the overall litter (puppies from larger litters tend to be smaller to start with, so doubling the weight at 14 or 16 weeks isn't very accurate for those; they will be larger generally). Even the size of parents is not that accurate. You really need to know the average size across a couple of generations, and the size of the litter and whether a puppy was average in the litter or larger or smaller.

A very VERY rough guide :D is that females will TEND to be about half their adult weight around 12-14 weeks, and males around 16+ weeks (males mature a bit more slowly). :) But that can be way off -- a small puppy in a large litter can easily end up far larger than double its weight at those ages.

So the calculator guessing a 12 week old puppy weight 2.45kg will end up an adult of 5.3 is probably a bit on the low side.

This is a note I have in the Library section from breeder Laura Lang:

Size: Healthy puppies, in normal weight, born in normal sized litters are usually half their mature weight at 3 months of age for girls (14 weeks or so) and 16 or 17 weeks of age for boys. If your puppy was born in a normal sized litter (3-5 puppies), was a normal size at birth, is not fat or thin right now, has always been healthy and is 7 lbs. at 15 weeks--he will likely mature out at about 15-16 lbs. If the litter size was less than 3 puppies he will grow faster at first and be larger at this stage than normal. If the litter size was more than 5 puppies he will probably grow a bit slower at first and be smaller at this stage than normal.

Note: Parental size has less to do with puppy size than 'family size'. In other words if the parents were the smallest in their respective litters they are highly likely to produce puppies more the size of most of the members of their family--or larger than they themselves are. You really can't go by the size of the parents much for this reason.
