Am after some advice please 
Our 8mo springer was castrated yesterday. He has one of the lampshade collars on but absolutely hates it. He's managed to claw it off twice already, and spends most of his time whining and trying to get it off, so not resting and taking it easy at all.
He's shown no interest in his stitches or sign of discomfort, just desperate to take the collar off.
I've checked it fits him ok and isn't rubbing him or anything like that. He just doesn't like it.
The nurse said it should stay on for 7-10 days, and I wanted to know is that really necessary?
