Dog swims in pool like the kids but goes after the kids

Hi,
I am no expert on Chesapeake's but I did own one for 10 years. I
rescued her from an animal shelter. She was a year old and her and her
litter mate were at the shelter. I consider myelf an experienced
trainer in obedience, but that was the one and only dog I could not
control. She was not aggressive, but she chewed up everything she could
get her teeth on. She ate the dashboard in my car (foam rubber). I
suggest you take the advice of the people that have posted here who are
knowledgeable about the breed and run don't walk to get a professional
trainer. I always dismissed her behavior as some genetic bizarre
malfunction but have later learned that it is certainly not a breed for
a novice and I certainly was. I loved her none the less. I wish you
the very best of luck.

Be Free,
Judy
