Labs can such different sizes it is hard to say. My dog is on track for doubling her weight at 4 months for her adult size.

 

Mine at 6 months and one week was 45 lbs.

Her sister was 42 lbs. a couple days before she was 6 months.

 

Mines almost 6 months

38 lbs

 

I wish I had a picture up, but my male was about 60lbs without being fat at around 6months. He was the big boy of his litter and he is a male. He's 8 months old now and his growth has slowed a bit but he's at 75 lbs last time I checked.

 

I have a female that will be 2 years old Oct . 5th and she tops the scales at a whopping 40 lbs . But size doesn't matter to me , she has more heart than most and can do the same work !!

 

My girl is 16mos and is 40lbs also
I thought I had the only one

 

I kept a record of mine hoping it could be helpful to someone in the future...I hope this helps..She's a yellow female and is now 10 months old at 62 lbs.
Here's her history:
2 months 2 days: 15lbs
3 months 3 days: 25lbs
3 months 22 days: 30lbs
5 months 0 days: 43lbs
6 months 0 days: 50lbs
7 months 6 days: 57lbs
10 months 0 days: 62lbs and still growing...

 

Our 1 year old yellow female is 60#.

 

My 12 month old female weighs 48 lbs, but her brother weighs 55 lbs. (littermates).

 

LOL i thougt the the same thing about mine Blk F. She is small like her father but not too small. She is 8mths and is around 40lbs. I figure she will top out around 55lbs. Perfect size for me and she retrieved a dead goose the other day so small in weight but really muscular in stature. Her father is the same way. I trained with a male her same age before she went off to training and he was twice her size! I prefer 60lbs over 90lbs personally

 

I wouldn't sweat it lab can have a huge range in size and theres nothing really bad about it. Females tend to run smaller. BTW my male chessie is 65lb and only five months...

 

Out of curiosity regarding this thread I weighed my six month old YLF but my scale is a digital and read error cause the two of us weighed over three hundred. So I had the wife hold her and she weighed in at approx 48 lbs.

 

My male was just over 60#'s at 6 months. He will be 7 months next week and will probably be just under 70 #'s. The problem is that he is a puppy, but doesn't look like it. There is a female in the neighborhood that is a week older than him, but about half his size.

 

Here is the weight chart I have kept. She was the smallest in her litter and looks to be on track to be about 60 pounds using the formula of doubling her weight at 4 months.

5/02/2009 7 Weeks 8.5
5/07/2009 8 Weeks 9.3
5/18/2009 9 Weeks 12.87
6/04/2009 12 Weeks 18.18
6/19/2009 14 Weeks 22.18
7/02/2009 16 Weeks 28.1
7/09/2009 17 Weeks 29.5
8/10/2009 21 Weeks 36.5
9/14/2009 26 Weeks 45.2

 

I don't remember the numbers exactly, but my CLF at 6 months was around 50 or so. The last time I had her at the vet at 10 mos. she weighed in at 65 lbs and had lost a little weight while sick (allergies). She's twelve months now and I bet is over 70 lbs.

 

I just weighed my little girl this afternoon and she will be 7 months next week and is 32lbs. To me she is small. Thanks

 

My male is 6 months now, and weighs about 58lbs. He's a big boy.

 

year n a half blm- right atourn 85-90 depending on the day n how much we have bin working, had him down to 83 over the summer, but i like a little fat for duck season

 

It also depends on the size of their parents.

Mine topped off at 63 pounds and I don't want her to be any bigger. She is perfect size.

 

Just weighed our month old pup .

 

My 4 month old Flat Coat in 27 lbs.

 

Don has been trying to slim down our 2 female black Labs. They are big girls. They were weighed on our vet's scale last week:

Ruby, 4 yrs old, a svelte 77 lbs. (she was 81 lbs.)
Sally (her daughter) 13 mo. old, 72 lbs. (she was 74 lbs.). It's hard to tell them apart. Tall, muscular, and very athletic.

Sally has some big brothers who at 13 mo. weigh over 80 lbs. They are not fat. They are just big boys. Our Labs are from "big dog genes".

 

Iwas worried about my Chocolate Female, she is 29 pounds at 4 months...her littermate brother was 46 lbs a week earlier! I guess some just aren't destined to be monster dogs

 

My chocolate female turned 6 mo last week...55lbs

 

Our 5 month old BLF hit the scales at 42# last week.

 

My six month old CLF is showing the small stock in her pedigree, weighs in at 29 lbs.
