Have a Question? Let us Know!

Please allow for 1-2 business days for emails and phone calls to be responded to. If the pharmacist is not available upon calling in, please leave a message and we will return your call. Please consult your veterinarian’s advice if you are unable to reach our pharmacist immediately and are in need of immediate assistance.

Please do not send us prescriptions by faxes or email. We are only allowed to accept faxes sent over from your vet’s office. If you have written RX scripts, you will need to mail the original hard-copy to our address. Please do not alter anything on original written prescriptions from vet clinics. All mail-in prescriptions are carefully reviewed, and veterinarians of clients whose prescriptions appear to be tampered with will be contacted for verification.
