New Toll-free Poison Control Number
The ASPCA has a new poison control hotline phone
number for pets. If you have reason to suspect that
your pet may have been exposed to something toxic,
either internally or externally, this phone number
will connect you with an ASPCA veterinarian specially
trained to assist pet owners or other vets.

This is the only dedicated animal poison control
hotline in the world manned by veterinarians, not
telephone operators. The number is staffed 24/7.

(888) 4ANI-HELP or (888) 426-4435

Please pass this on to other lists and animal owners
