8mth old working cocker

Question
How much should Scooby weigh at 8 months?

He was wormed on 10th May when will he be due to be wormed again?

Answer
It's impossible to give you an exact weight since I don't know how big a boy he is but you shouldn't be able to see his ribs and you should be able to easily feel them.

In general, at 8 months he'd probably weigh between 17 and 20 lbs.

I wouldn't keep worming him - take a stool sample in to your vet and find out if he needs it.  Stool analysis should be done annually unless you have reason to think he has worms and even then you'd check the stool first.
