You ask: Are Papillons, Phalenes sensitive to vaccinations, puppy shots.

You asking about the sensitivity in Papillons to vaccinations, or puppy shots.
Papillons, and Phalenes are no different than any other toy breeds.

Puppy vaccinations have saved many of lives, but there are some puppies that will have allergic reactions to a vaccines.

The most common reaction generally just makes the puppy feel listless for a couple of days but in a rare case they can have an anaphylactic shock.

The signs of anaphylaxis include vomiting, diarrhea, seizures, pale gums, weak pulse, facial swelling, a fast heart rate and cold limbs.

The risk of a puppy catching a disease, followed by death is much, much higher, than the chance of having a reaction to a vaccination.
