My moms dog did something like that to my dog..
My mom's dog must have been VERY thirsty... we were at the beach and I filled a cup with ice water, and lowered it down for my dog to drink.
My moms dog walks up and TIPS the cup in my hand causing the water to go in his nose.... <yes, he did choke on it for a minute>
I'm just surprised how my dog didn't do it back. *maybe cuz he's an idiot?*
