Owning a dog or cat is a joy. That little bundle of fur just oozes unconditional love and devotion. But it's not all fun and games. Pets, unlike that carnival monkey you won by spraying water into a clown's mouth, need shots and medication. And, like humans, they get sick. So what do you do when Fido is filled with fleas or Tiger is yakking all over because she ate a bad lizard? You take your little friend to the Coconut Grove Animal Hospital. It's been around since 1965. One look at the wood paneling reveals that nothing has really changed since then — including the old-fashioned care you would have expected 40-some years ago. Dr. Michael Marmesh Jr. and his daughter Dr. Kate Marmesh attend to your darling with the gentleness of a small-town vet who stepped out of the pages of the Saturday Evening Post. The clinic is open six days a week and you don't need an appointment (except for surgery, dental work, and boarding), which means that if you forgot to renew Minky's rabies tag the day before your big vacation, you can just waltz her right in and be seen. Don't you wish your shrink had the same open-door policy?
