Vomiting in dogs: what to do

The most common digestive problem, usually from diet indiscretion (scavenging, sudden food changes) or mild infection.

A highly contagious viral disease attacking unvaccinated puppies, with high mortality — earlier treatment means better outcomes.

Swallowed toys, socks or bones block the intestine; persistent vomiting is the earliest sign.

Often triggered by a fatty feast (table scraps, fatty meat); Schnauzers and similar breeds are higher risk.

Chocolate, xylitol, rodenticide, antifreeze and more can be fatal; onset speed varies by toxin.

Roundworms, hookworms, tapeworms and more — common in puppies, causing anemia and malnutrition.

A balance-system (inner ear / brainstem) problem: sudden head tilt, flicking eyes and stumbling. Idiopathic geriatric vestibular syndrome is the most common form and mostly resolves in days to weeks — but ear infection, toxins and brain disease must be ruled out first.

A post-heat emergency of unspayed females: the uterus fills with pus and toxins. The open form shows vulvar discharge; the closed form hides it and delays diagnosis. Spay surgery is the only cure.

Dogs can only cool by panting — hot, humid or enclosed conditions (cars!) can kill within minutes.
