help please

I have 2 beautifull staffies, aged 2 & 3 (Holly and Purdey). My problem is when I my Purdey everything went wrong. Holly was so well behaved but when we got Purdey their behaviour went out of control and now I'm struggling to cope with their antics. I know they love and are very protective over me, which is nice. I want this to continue but really want them to behave themselves. Any ideas people?

What is it that they are doing exactly?

Yeah if you could list the things they are doing. Also how long you have had Purdey for?

Also why don't you come and introduce yourself. Don't worry we don't bite

A little more info would help

We really need to know exactly what they are/aren't doing.

If you can give us some more info we'll try our best to help. ><

Please come back and tell us a little more. I have 2 myself (both from pups) and know a bit about how behaviours can change to readjusting, change of attention etc but we need a bit of info
