A healthy dog or cat w/a good strong immune system can handle salmonella, that is why they can eat raw meats. A dog or cat w/compromised immune system are more @ risk.

There are more than 2,000 different types of Salmonella, a Gram-negative enterobacteria. Typically, a host animal carrying the disease will have two or more different microorganisms or types of Salmonellae bacteria that cause this disease.
Risk factors include the dog's age, with younger and older animals most at risk due to their underdeveloped and/or compromised immune systems. Similarly, dogs with weak immune systems or immature gastrointestinal tracts are at risk.
Dogs receiving antibiotic therapy are also at risk because the healthy bacteria that line the digestive tract (or florae), may become imbalanced, increasing the risk of salmonellosis. |
