Frequently Asked Questions
My puppy just licked an unvaccinated dog at the park – what do I do?
That's scary, I get it. Deep breath – one lick is low risk for parvo, but not zero. Don't rush to the vet unless you see symptoms. Instead, monitor your puppy for vomiting, diarrhea, or lethargy for the next 10 days. Call your vet tomorrow to discuss the exposure and ask if they recommend extra precautions. In the meantime, wash your hands and keep your pup isolated from other dogs until you're sure no symptoms develop.
How can I tell if my puppy's vomiting is from parvo or just an upset stomach?
Upset stomachs usually happen once or twice, and the puppy stays alert and thirsty. With parvo, vomiting is frequent, often yellow or bile, and is soon followed by severe diarrhea (often bloody). The puppy will become lethargic, stop eating, and may have a fever. If the vomiting continues for more than a few hours or is accompanied by any weakness, get to a vet immediately.
When exactly is my puppy considered fully vaccinated?
Full vaccination means the puppy has received all core vaccines (DAPP/parvo, distemper, adenovirus, and rabies) according to your vet's schedule, and at least 2 weeks have passed since the final booster. For most puppies, that's around 16-18 weeks of age. Some vets consider the puppy protected 2 weeks after the second DAPP shot (around 12 weeks), but it's safest to wait until the full series.
If socialization is so important, why can't I just take the risk and let my puppy meet any dog?
The risk isn't just a small chance of a cold – parvo has a 10-20% mortality rate even with treatment, and distemper is often fatal. Treatment costs thousands of dollars and your puppy will suffer badly. Early socialization is crucial, but you can achieve it through humans, sounds, objects, and controlled dog meetings – without gambling on diseases that are preventable.
I'm scared my puppy will become aggressive if I don't socialize them with other dogs right away – what should I do?
That worry is totally normal, especially with breeds known for reactivity. Here's the thing: you can still socialize your puppy without meeting random dogs. Expose them to different environments, people, noises, and train calm behavior around dogs from a distance. The formal 'dog socialization window' closes around 16 weeks, but you have until then to build positive associations – and safe, vaccinated dog friends count! Don't risk your puppy's life for the sake of a few playdates.
My puppy is 8 weeks old and has had only the first shot – can he meet my neighbor's adult dog who is fully vaccinated?
Yes, with some conditions. If the neighbor's dog is fully vaccinated and healthy (no symptoms of any illness), and the meeting takes place in a clean, private yard or home (not a park or sidewalk), it's generally considered low risk. Still, watch both dogs closely – your puppy may be intimidated by an adult dog, so keep the interaction short and positive. And monitor your puppy for the next week.
