Pet Vaccination & Reproductive Surgery Schedule

Current dog and cat vaccinations are required to protect your pet from a variety of contagious, often fatal, diseases. Spaying or neutering your pet not only prevents unwanted litters, but these common veterinary surgeries can also help to protect your pet from some serious cancers. They have the potential to prevent undesirable behaviors like howling, scooting, roaming, and aggression.

Parasite Prevention

Parasites are a serious health risk to both humans and animals in the Port Jefferson region. Parasites, if left untreated, can endanger the life of your cat or dog and, in some cases, can be transmitted to other people or pets in your home. Our parasite prevention products can help keep your dog or cat safe from the following parasites:


Fleas are external parasites that feed on the blood of birds and mammals. Left untreated, fleas can quickly spread throughout your household.


These external parasites consume the blood of mammals and are responsible for spreading several serious conditions in people and pets. 

Ear Mites

Tiny, highly contagious ear mites reside in the ear canals of dogs, cats, and other mammals. These parasites continuously reproduce during their life. 


This thread-like parasitic worm spreads through mosquito bites and makes its home in the heart, lungs, and blood vessels of infected animals.


These parasites live in the digestive tract of cats and dogs and feed on the pet's blood. Hookworms can lead to anemia and other conditions.


This parasitic worm lives in the intestine and feeds on partially digested food. This parasite can rob your pet of vital nutrients they need to stay healthy.


Tapeworms are spread through the ingestion of infected fleas during grooming. These hook-like parasitic worms live and grow in your pet's intestines. 


Whipworms are spread through the ingestion of soil that has been in contact with an infected dog's feces. Whipworms pose a serious health risk to dogs.
