You could be describing my Ben, who is show not worker. But he was a difficult bitey pup, who turned into a challenging bitey, stroppy teenager, but grew into a complete cuddle monster, much to my shock (and delight). Nearly 12 years ago when he was a pup, I didn't have Col and he was our first dog, I didn't know anyone with a cocker either so had no idea what was normal. But I can remember crying with frustration when every time I said no or tried to stop Ben eating something outside he would just launch at me mouthing and biting. He even used to lie on the floor kicking and screaming like a toddler. I had no idea what to do
. we had some very dodgy advice, as at the time 'dominance' theory was the big thing, and we made lots of mistakes which I think have left the few remaining issues Ben has.
Fortunately things have changed for the better and a good behaviourist can help and advise up how to manage the behaviours and what to do, using positive methods. Ben was a poo eater for years, and partly because I had no clue what to do and partly I was embarrassed as I had no idea how common it was I ignored it, however when we did have some help it stopped in a few weeks and hasn't really been an issue since.
No one was more surprised than me at how Ben turned out, he wasn't knicknamed Alien for nothing, think lots of teeth and drooling while trying to eat you...
. It is so worth the effort, to get past this stage, as we ended up with a loving, cuddly dog. I am sure Bob wil turn out just fine, but do ask for help from someone experienced as you want to start enjoying walks not dreading them. If you say what prof the country you are in someone might recommend a good behaviourist.
