Cockroaches are not only associated with loathing and disgust but can also carry dangerous bacterias, including Salmonella, Shigella, Campylobacter, Pseudomonas aeruginosa, and Klebsiella pneumonia (Source). Moreover, cockroaches can also trigger allergies and asthma episodes.

Despite these facts, you still don’t have to worry at all if a dog eats a roach. The reasons being,

Moreover, like humans, cockroaches are also known to trigger allergies in pets, including dogs (Source).
