Let's see, the last time I had my other 2 at the vet, Buck was 3 1/2 weighed in at 69 lbs, very tall and rangy, Tia was 2 1/2 weighed in at 65 lbs...Samson at 10 1/2 weighs 85 lbs, and Angel at 2 yrs(almost) weighs 55 lbs...There is no right or wrong for weight. Yes there is a breed standard, but you know your dog..Some can carry more weight, but as long as you are seeing a couple ribs and no spine, they should be fine. Excess weight is not good on the joints, Samson is still needing to lose a bit more and at his age, every pound lost is better on him..
