My senior dog won't eat for days and sleeps a lot. What's wrong?

Poor Ruka sounds very ill at the moment. Anorexia (not eating) is a very general sign of many illnesses, which could be caused by dental problems, systemic illness, infection, inflammation, or injury. She could have have a hard time breathing because she has a respiratory infection or cardiac disease. Being quite sick would lead her to seem very weak. I strongly recommend a vet visit as soon as possible for her. The vet can diagnose what is causing her symptoms, and can treat her for it. Best of luck, I hope this helps!

Barbie sounds extremely ill, and her anorexia could be caused by a systemic illness, infection, inflammation, or injury. This is a medical emergency and she needs veterinary attention now. Please bring her into a vet right away.

Pasha and her sister are adorable together! From your description, it sounds as though Pasha is quite sick. Extreme lethargy and a decreased appetite can occur with a number of health conditions, including kidney disease, liver disease, bleeding masses from the spleen, serious viruses, or cancer, among other conditions. At this point, I strongly recommend taking Pasha to her vet for evaluation. She will need a full physical exam, and will likely also need additional diagnostic testing, such as blood tests, chest and abdominal x-rays, or abdominal ultrasound, to try to get to the bottom of this situation so that treatment can be started. I hope this helps and that Pasha is feeling better soon!

I am so sorry to hear that Doggy is sick. But not eating is a very general sign of illness and she needs bloodwork anlaysis + urinalysis to look at her body systems to determine what the underlying cause of her ailment is. Also she is an older dog so neoplasia (cancer) has to be considered if all her labs come back negative, at which point further testing like an ultrasound or radiograph would be indicated. Your pet is very sick and will need proper testing to find the cause and hopefully there is a treatment specific to her disease condition available that can hopefully give her a good quality of life back. If her prognosis is deemed poor based on the findings, then palliative care (meds to make her comfortable from your vet) may be her best option.

Poor Charlie sounds like he is ill! Anorexia is a very general sign of illness and it can be caused by dental problems, systemic illness, kidney disease, liver disease, heart failure, infection, inflammation, injury, or even cancer. When a dog feels poorly, there are often behavioral changes and that may be why he doesn't care when you lift him. I would have him seen by a vet as soon as possible. The vet can diagnose what is causing his symptoms so he can be treated. I hope this helps!

That is a very severe condition and prolonged starvation can lead to critical clinical status. Nutritional support, fluid therapy and investigations of the underlying cause of chronic anorexia are required immediately. I would strongly recommend a check up at your local vets whatever is the cause of the signs you described.

Panting heavily when it is not hot in the environment is usually a sign of pain or discomfort. If Mia has had a poor appetite for a few days, it is possible that she has a chronic condition such as liver or kidney disease that can be diagnosed on routine screening bloodwork. Unfortunately at age 12, especially for a large breed dog, serious/not curable conditions such as cancer (usually diagnosed on chest/abdominal X-rays) is a possibility as well. Less scary possible causes of the panting could be discomfort from pancreatitis which is often caused by table food and treated with fluid therapy +/- anti-nausea medication, or pain from arthritis which can be treated with pain meds pending screening bloodwork to rule out pre-existing liver/kidney issues. Especially since Mia seems uncomfortable, it would be best to bring her to your vet for an evaluation. Good luck!
