This is a somewhat disorganized list of resources, articles and references which dog owners may find interesting.
The nearest 24-hour emergency veterinary clinic is Veterinary Emergency Referral Service in Cobble Hill. Their web site was acting up when I posted this so here's the Google reference, which includes a map, address and phone number.
You should keep ASPCA's Poison Control Hotline number handy too: (888) 426-4435. I called it when Jack ingested a Frontline capsule. It's $55 per call, billable to a credit card.
