When I was a young child and our family visited a body of water to swim in my parents instituted the the belly button rule. The older, more proficient swimmers could swim out to rafts in the middle of the lake or play in the waves, but the little kids could go no deeper than their belly buttons. If we lost our footing we would be safe and it was deep enough for us to pretend to be swimming. With our hands on the bottom of the lake we could kick our feet, put our faces in the water, blow bubbles, all the skills that one needs in order to swim, for real.
People living with fearful, shy or reactive dogs are often reluctant to limit their dog’s opportunity to go out into the world, for walks or car rides because they feel as though they are depriving their dog of exercise or variety. It’s thoughtful to take a dog’s needs in these areas into consideration, but not if they routinely end up over their belly buttons and have a bad experience because of it.
I remember wanting so badly to be able to swim with the big kids. My father shot Super 8 movies of me putting my entire face into the water and then coming up, wiping the hair and water from my eyes triumphantly. This was a milestone enroute to becoming a swimmer. My parents did not feel guilty that they were limiting my exposure to deeper water. They did not impede my ability to learn when they called me in when I went too deep or my lips turned blue and my fingers wrinkled.
Until a dog has the skills to come into contact with the things that cause them to react negatively, don’t risk them getting in over their heads. I didn’t have to almost drown to learn to learn to swim.
