“In dog beers, I’ve only had one”

“In dog beers, I’ve only had one” is a popular T-shirt slogan. The slogan implies that a six-pack of beers equals only one in “dog beers.”
 
The saying has been cited in print since at least 2005.

Lifespan
The old rule-of-thumb that one dog year equals seven years of a human life is not accurate. The ratio is higher with youth and decreases a bit as the dog ages. Depending on breed, a dog experiences the raging hormones of adolescence anywhere from eight months to two years or more. Generally, a dog of six has aged about as much as a 45-year-old human. At 10, she’s like a human of 65; at 12, a human of 75; and at 15, a human of 90.
