Hi and welcome to ST

we have poppy and she is just coming up to 5 mths now, we have found with the chewing that kongs filled are a great way to stop them having a pop at your sofa and also using a crate when you are out (only for short amounts of time) are perfect to allow you to come home to a intact house.

Also playing lots of games that include training (although they think its a game

) are perfect for wearing them out metally which with Poppy (who up to now with all my fingers crossed has not chewed anything she should not in the house) doesnt allow her to get bored and so start chewing things she shouldnt. Its not just the physical excercise springers need its also the mental and they from what I have heard can drive themselves potty with nothing to do.
With the pulling like has been said its a springer thing by the looks of it

although ive just ordered me a gun dog training book so I will let you know how I get on.
I hope thats of some help, as like I said weve only been puppie owners for a while ourselves. Also ask lots of questions on here as they are great.
EDITED as this morning i can not seem to spell to save my life
