My Chihuahua suddenly arched his back, staggered, then was fine. Why?

Any abrupt behavioral change is a good excuse to get him in to see your vet. He may be starting to develop a medical condition that should be investigated but it's so early that the only symptom he is displaying is this strange behavior. There may be something happening periodically that is making him uncomfortable of the feeling comes and goes, but either way, it should be looked into by your vet. Your vet will do a thorough exam, possibly some x-rays and/or bloodwork, as indicated. Based on these results your vet will have a better idea what is going on and be better able to advise you as to what action should be taken.

Sorry we couldn't get to your question earlier! Hopefully Carlos is back to normal now. Marijuana toxicosis can have a variety of signs based on how much was ingested and if it was an "edible." It does sound strange. If he continues the behavior after waking up, then evaluation by a vet is indicated. I would be concerned about possible neurologic disease, hypoglycemia, or heart or lung disease.

Since I am unable to examine Tia, I would have her examined by your veterinarian to ensure this is nothing serious. If she is acting strange, she could have had a seizure or may be about to have seizure. Certain systemic illnesses may also exhibit similar symptoms. I would definitely get her in for a full workup to be on the safe side. Please feel free to contact me with any other questions / concerns you may have. I am also available via consultation.

Poor Lily! It sounds like she could be suffering from back/neck pain or muscle spasms. I would have your vet take a look at her as soon as possible. Your vet will be able to determine the cause of her pain or weird behavior and get her started on the proper meds if needed to help her feel better. I hope this helps!

Poor Little Man. I recommend to have an x-ray to look for evidence of disease in his spine. This sudden pain could come from many things including intervertebral disc disease, discospondylitis, an anal gland infection or a pinched nerve. The x-ray could show evidence of the first two diseases. Discuss start medications like steroids and muscle relaxants with your vet as well. Have the anal glands checked as well. An omega 3 fatty acid supplement for dogs may also help but will not control the symptoms alone. I hope this helps and please feel free to post any additional questions.

This is actually a sign of abdominal pain. Common causes are pancreatitis, gall bladder disease and intestinal disease. The incident with the couch appears to be a separate issue and not serious if he is waling fine. It's best to have Toby seen by a vet sometime soon, so the specific problem can be identified. If he does the pray stance/shaking again, then it would be best to take a video to show to the vet. I hope that helps and Toby gets better soon.

Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach! This is hard one... it is difficult to say exactly what is happening to Ace here without doing an exam first. This behavior you mentioned could be many things- it could be spinal pain, focal seizures, or another neurological condition. I would highly recommend Ace see his veterinarian for an exam soon. You may also want to capture a video of these episodes on your phone to show to your veterinarian as this may help aide in a diagnosis.
