I just wanted to note that Tucker is now one and we have noticed a major change in his behaviour lately. He is still crazy, still nippy, still a cocker but we are noticing more quiet moments in him.
Tucker is still battling some anxiety issues and we are working with our vet on that, but we are starting to notice less craziness and more normal dog behaviour. He is incredibly bright and needs a lot of stimulation. I have to wonder if that wasn't part of the problem. Our last cocker was so well-behaved and so loveable but not have as bright as Tucker is (I don't mean that in a bad way!). Tuck is just incredibly smart....perhaps too much for his (and our) own good.
We walk him a lot and need to spend more time on training as it seems to be what really keeps him on his good behaviour. He also knows "no bite" now which is a HUGE acheivement for him. Mind you, when he's playing it seems like his brain turns off completely at times and there are moments when he's got a hand in his mouth and we're yelling "no bite" where you can almost see him come out of his crazy world and realize what he's doing.
We never thought we'd make it through that first year and we're on the other side now and looking forward to the next, good and bad.
