You shouldn't need to weigh a dog to know it's at it's proper weight, your eyes should be able to tell you all
you need to know, if they can't you've got a problem.
Just for you I've weighed my dog he's 24" tall and weighs 51lb.
He's 3/4 grey/ 1/4 collie X whippet/ [3/4 grey 1/4 collie].
I fully agree with regards to condition mate, but when it comes to worming, you need to know weight in order to give an effective dosage.
I'll be very honest with you mate. I just said it to goad folk into responding. Sorry. . . . but it worked. Haha. Trust me what i said will be nieth
