Why is my puppy suddenly shivering, scared, and has a high heart rate?

If only Oreo could talk! This type of behavior could be related to something like anxiety or to pain/discomfort. I recommend to have her examined by the veterinarian who will check for evidence of pain on the physical exam. They may also check a urine sample or the anal glands as well. Since she can't talk, it's best to play it safe. Best of luck.

I can certainly see how this would be very alarming to witness. The symptoms you describe may be related to a disease process affecting an organ system (more often the neurologic (seizure event) or cardiac (heart event) systems). What i would recommend is a visit to your family veterinarian for a physical exam, to discuss the events, and to discuss additional testing (like bloodwork to rule out organ changes). It is also extremely helpful to get a video of an event so that your vet can watch it. Also, given the age of your pup, make sure there is nothing new in the environment that he could be snacking on that may be toxic to dogs (plants, etc.). I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!

Poor Grace! If you can't find an obvious cause for anxiety, it's best to have her checked out for pain as pain can make pets behavior this way as well. Pain can be in many forms including back pain, pain from the pancreas or bladder pain. Since she can't talk and tell you why she is acting this way, it's best to play it safe. Try to keep her quiet and keep the house quiet and non-stimulating and pay close attention to her eating/drinking/bathroom habits until you get her in for her exam. I hope she starts feeling better quickly and please feel free to post any additional questions.

There could be a couple of reasons why Rosie is shivering. Shivering could be caused by pain, fever, anxiety, or nervousness. Given she recently saw the vet and had had no problems, I would suspect nervousness might be the cause. She's new to your home, and that is a stressful adjustment. As long as she is eating and drinking normally, going to the bathroom normally, and otherwise acting normal, I would not be too concerned about it. I hope this helps!

Since this is a behavior without appropriate context (like thunderstorms), I would recommend having Lily examined by a vet. These types of behaviors can be similar to pain responses, difficulty breathing, heart arrhythmia, pre-seizure activity, etc. The vet will do a thorough exam and discuss Lily's relevant medical history to determine if additional diagnostics are necessary.

I would recommend that you have Bella examined by a vet as soon as possible. Open mouth breathing in a dog that is in a cool, comfortable environment can be caused by heart disease, lung disease, anemia, severe pain, among a few others. Rapid heart rate can also be caused by these things. When you get to the vet, they will do a physical exam and may recommend x-rays to make a diagnosis.

Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach! Although Mya is still eating, drinking, and having normal bathroom habits, the shaking and lethargy is a concern. Shaking can sometimes be an indication of pain or discomfort in dogs or can be a symptom of certain endocrine diseases. I would recommend having her seen by a veterinarian as soon as possible. In this case, it is very hard to say for certain what is going on with Mya without examining her first. A veterinary exam would be a good place to start so she can be evaluated head to tail. Your veterinarian may recommend blood work and/or x-rays be run on Mya as well to help determine a diagnosis. I hope this helps and thanks again for posting!
