If your dog has esophageal dysfunction, like when the muscles tend to fill with water or food, which builds up and leads to problems, you must consult your vet. Sometimes, they administer the drugs to increase muscle movement, and antibiotics are the secondary aspiration.

In simple cases of bacterial infections, clean water is given to the dog, along with a bland diet of white meat like fish or chicken with boiled rice.

In the blue-green algae exposure, your dog needs the immediate attention of a vet. It mostly happens in the hot summer months. If there is no antidote for the toxin produced by the algae, get immediate support from your veterinarian.
