Why is my dog suddenly anxious, panting, and trembling without cause?

These can be symptoms of many serious medical issues, anxiety, fear, pain, neurologic disease, infection, etc. I would recommend that you have him checked out by a vet to see what could be going on. After a thorough physical exam and discussion of his recent history, the vet may recommend diagnostics, such as blood work, x-rays, ultrasound, etc. to diagnose the cause.

Hello! I'm sorry to hear that Eleanor might not be feeling well. There are several things that I think of when I hear about dogs that are trembling or shaking. First, dogs that tremble and shake may be experiencing pain. Conditions like luxating patellas (kneecaps that pop out of place) and back injuries come to mind with smaller dogs like Bichons and Shih-tzus. You may not have seen the initial injury, but if they "tweak" an old or chronic injury, it can make them shake, pant, and want to be clingy, as they don't understand why they are hurting. Next, behavior changes in middle-aged dogs could be caused by metabolic disorders, like hypothyroidism or Cushing's disease. I would also expect to see other symptoms with these disorders, like weight changes and a poor hair coat, so if you see any other physical changes, this could account for Eleanor's shaking. Lastly, stress can also cause shaking and trembling behavior (like from storms or major construction going on in the neighborhood). I definitely recommend having Eleanor evaluated by a veterinarian for pain and/or other disorders before chalking her trembling up to a behavioral issue, as many conditions like pain and hypothyroidism can be managed with treatment, and she'll be much happier for it. Good luck, and I hope that Eleanor gets better soon!

I'm sorry to hear Chiquita isn't doing well. If she's seeming in distress, unable to breathe or is very pale/turning blue, or seems in discomfort or is disoriented, it would be best to bring her to a vet ASAP for care. Stress or pain can also sometimes cause these symptoms. Making sure there isn't a sudden stressor causing, or removing any sources of stress may help her to calm down, however if the symptoms continue or worsen, or new ones appear, seeking vet care is best.

I am sorry ot hear about Quica. Shivering and panting can be a sign of extreme anxiety, pain, respiratory distress, ingestion of a toxin, and more. If she is continuing this behavior and there is nothing going on that could be causing anxiety (such as fireworks or loud noises), I would recommend bringing her into the vet for an examination.

These types of behaviors could be caused by pain, anxiety, internal medical issues, cognitive dysfunction from old age, seizures, etc. Without seeing a vet, it is hard to tell what could be going on and I can't really make any specific recommendations. Be available to comfort him. You can also try doggie pheromones like Comfort Zone or Adaptil.

Since she can't talk and tell you why this is happening, I recommend to have her examined quickly by the veterinarian. It's possible she is in a lot of pain and that's why she is acting this way. It's not likely old age. I hope the doctor figures it out quickly. Please feel free to post any additional questions.

Any abrupt change in behavior without a known cause should be investigated by your vet as soon as possible. Sometimes this is the only sign we get of a medical condition. The behavior could be due to feeling ill, being in pain or may be because of a developing neurological condition. Your vet will do an exam, labwork and possibly some diagnostic imaging, x-rays or ultrasound to determine the cause for your pet's change in behavior and, based on the results, will be better able to advise you on treatment options.
