I was just what is the weight range for an average 4 month old female lab. Thanks!
Huge span, depends so much on growth rate and heredity. Best to ask your vet.
Hershey Kisses, In charge of getting Ed out to the dog park so that he gets some exercise.
Average for the standard, including my experiences is ~30 lbs. A small dog and a large dog would be different, additionally some dogs just grow at different rates.
Maggie is 14 Weeks and 26.5 pounds.
My five month old is 29 pounds.
We are one day away from 14weeks, female black lab, and we are at 27.3lbs.
This is a very common question. Unfortunately, there's no definite age/weight answer.
Here's a copy of a post I've often made:
There's no meaningful average for Lab puppy weight gain because there are so many different lines and some young adults level off at 50 lbs (or less) while others level out at 125 lbs (or more).
I measured my Puff's weight gain regularly. Her rate of growth followed a curve similar to the silhouette of the NW quadrant of a US/Can football when its noses are pointed EW.
Reading off her growth curve (wght X Day's Age) I plotted:
At 65 days, she weighed 6 lbs. (65 dys = 2 mos, 5 dys)
At 105 days, 20 lbs. (3 mos, 15 dys)
At 145 days, 31 lbs. (4 mos, 25 dys)
At 185 days, 42 lbs. (6 mos, 5 dys)
At 225 days, 47 lbs. (7 mos, 15 dys)
At 265 days, 52 lbs. (8 mos, 25 dys)
At 305 days, 54 lbs. (10 mos, 5 dys)
A friend has a male Lab from a BYB; he was born on the very same date as Puff and always weighed twice what Puff weighed at the same age.
But I've seen a study published (in JAVMA) by vets at Seeing Eye in N.J., on growth rates for the Lab line they breed. Instead of being a concave curve like Puff's, theirs is sinusoidal (a stretched out S-shape): their Labs initially gain weight at a slower rate than Puff and her friend did for about the first 5 months, then accelerate more rapidly, and then level off.
So -- it all depends. There's no one pattern. Perhaps your Lab breeder has typical data for your line?
Puff [YF, AKC field line (from competing HT/FT breeder) 62 lbs, dob: 8-'01]
Bess [BF, AKC bench line (from competing show breeder) 55 lbs., 1967-1981] "Poor Bess, the Wonder Dog":
Well, my puppy will be 4 months old on tuesday and now weighs in at 43 lbs!!! He is a big boy but healthy according to our vet.
Koda is about 15w and she is around 33lbs(ish). (her parents were huge).
