PetSmart stores are warning dog owners to protect their pooches from getting salmonella from some treats sold at its stores, the U.S. Food and Drug Administration said.

Two types of Dentley beef hooves sold between Oct. 2 and Nov. 3 are being recalled over fears they could be contaminated with the bacteria. They are:

• Dentley's Bulk Cattle Hoof UPC# 73725703323
• Dentley's 10 Pack Beef Hooves UPC# 73725736055

Both have a use-by date of Oct. 14, 2012.

The FDA said that although the products were shipped from the Pet Carousel manufacturing plant to only three PetSmart regional distribution centers, the company was pulling the product from its stores nationwide as a precaution.

Consumers who have the products should not feed them to their pets, and should return them to any PetSmart store for a refund. Those who have fed them to their dogs and are concerned should contact a veterinarian.

Dogs do not necessarily show the same signs of salmonella poisoning as humans, but can suffer from diarrhea and have other symptoms.
