Why is my old dog whining, breathing hard, and struggling to lie down?

In a dog Bailey's age, yes there is a chance it could be heart failure . You will need to take her into the vet now. The vet can do a physical exam and x-rays to see how her heart is working, and if she is in heart failure, the vet can prescribe medication to manage her symptoms. Best of luck.

If your dog is an older dog, it could be that she is suffering from arthritis and it's painful when she lays down. I would her seen by a vet in the next couple of days for this problem. It could be that she would benefit from some pain medications, which the vet can prescribe.

I am sorry to hear about Alfie! Shaking and inability to sit still/get comfortable easily can be a sign of pain/discomfort so I would recommend a visit to his veterinarian for an exam. It is possible he could have some musculoskeletal pain, pain from the anal glands, or pain/irritation of the skin if his itching issue hasn't been treated. The vet can perform a good physical examination on him to help determine what is causing his discomfort and treat it appropriately.

Poor Buddy! I'm sorry to hear that he's having this problem. From your description, I would be concerned about a possible neurologic problem such as a stroke or brain tumor. He may also have severe arthritis issues, or may have a systemic illness of some kind or may have ingested something toxic. This sounds quite serious, so I would recommend taking him to an emergency clinic this evening for an exam. The veterinarian there can do blood work or other testing if needed to help diagnose the problem and see what can be done to help.

If your dog is lying in the "prayer position" - front end down and rear end up - while acting uncomfortable, it's usually a sign of abdominal pain. It sounds like your pup isn't feeling well for some reason. You can try offering her a bland diet of plain boiled chicken and rice for today to help settle her stomach. If this doesn't help, or if she develops any other symptoms such as vomiting, not wanting to eat, or acting lethargic, then I would recommend having her examined by a vet as these can be signs of a serious GI problem such as pancreatitis.

He needs to be examined by a veterinarian right away. Your vet can take an x-ray of his chest to evaluate his lungs and airway. He could have pneumonia, asthma, heart disease, or fluids in his chest. Please call your vet immediately and schedule an appointment.

pacing, crying when touched, hiding, panting are all signs of pretty severe pain. You need to take Willie to your vet for an exam, x-rays, and possibly blood tests to find out why he is in so much pain. Your vet can then assess the condition and prescribe relevant medication to make him feel better, such as pain medicine.
