What do you when your Jack Russle terrier is sick?

I'm sorry to hear your Jack Russell terrier is sick. As an AI, I can't provide medical advice. You should always consult a veterinarian for any health concerns your dog may have.

However, I can provide some general tips that might help you until you can reach a vet:

* Observe your dog closely: What are the symptoms? When did they start? How severe are they? This information will help your vet diagnose the issue.

* Take their temperature: A normal dog's temperature is between 100.5 and 102.5 degrees Fahrenheit. If your dog's temperature is higher or lower than this, it could be a sign of illness.

* Restrict their activity: Give your dog a quiet, comfortable place to rest.

* Make sure they have access to fresh water: Dehydration can make illness worse.

* Don't give them any medications without consulting a vet: Many human medications are toxic to dogs.

It's important to act quickly if your dog is showing any signs of illness. Even if you think the problem is minor, it's always best to err on the side of caution and seek veterinary advice.
