It is important that you take your vet for a checkup every year. During the visit, the vet will make sure that your pet is healthy and free of disease. They will also take the opportunity to make sure that your pet is up-to-date on his shots. There are also emergency situations where you will need to take your pet to the hospital. Certain issues would be considered an emergency.


There are many ways that your pet can get injured. Being hit by a car, being in a fight with another animal, getting stepped on by a human, or falling from a high up place can all cause your pet to be injured. If your pet suffers an injury, it is considered an emergency. When you take your pet to see the vet, they will make sure that there are no broken bones and internal injuries. Since many injuries can be life-threatening, you should take your pet to the veterinary clinic as soon as possible.

Excessive Thirst

If it is especially hot, your pet may be more thirsty than usual. If it is not hot outside and your pet is excessively thirsty, you should take him to the vet. Excessive thirst could be a sign of diabetes or kidney problems, which are considered emergency situations.

Excessive Vomiting or Diarrhea

It is not uncommon for a pet to vomit occasionally. The same is true with diarrhea. This is because pets often eat things that they shouldn't. However, if your pet has gotten sick several times over the last couple days, he should see a veterinarian as soon as possible. Excessive vomiting or diarrhea can cause your pet to become dangerously dehydrated if not treated quickly. Not only will the vet treat the dehydration with fluids, but they will also find the cause of the vomiting or diarrhea.


If you believe that your pet has ingested something poisonous such as human medication, pest control poisons, chocolate, grapes, a slug, you should take him to see the vet immediately. If your pet digests and absorbs these poisons into his digestive system, it can be life-threatening.

Difficulty Breathing

Wheezing, shallow breathing, coughing or choking are all emergencies. Your pet's breathing issues could be due to a foreign body in the throat, an allergic reaction, lung disease, heart disease, or asthma. It is essential that your pet is treated immediately to get to the root of the problem.

If you believe that your pet is suffering from an emergent condition, you should take him to Allenstown Animal Hospital. The vets at our animal hospital can examine your pet to determine the cause of their symptoms. The sooner you take your pet to our emergency veterinary clinic, the sooner the problem can be treated.
