My senior dog is losing weight rapidly and won't eat. What to do?

I'm sorry to hear that Abby isn't eating! I would recommend taking her to the vet for an exam as a first step, since there are many medical issues that can cause a loss of appetite in older dogs. Many of these issues can be treated once a diagnosis is made, so there's a good chance your veterinarian will be able to help. He/she will likely recommend blood work and possibly x-rays of her abdomen as a starting point, and will advise you on further testing and treatment options from there depending on what is found.

If the weight loss is more than 10% of the her body weight, this could be abnormal and should ideally checked. Gastrointestinal abnormal absorption of nutrients may be present and should be investigated. Usually chronic gastrointestinal inflammations/infections are responsible for it. I would start with a blood test and some imaging procedures of the abdomen (an ultrasound).

I would definitely recommend some blood work, if this hasn't been done recently. Older dogs are prone to a number of health issues that can cause decreased appetite along with being less active - chronic kidney disease and hypothyroidism are two possibilities that are both very common. In many cases, these issues are treatable (at least to some extent) once a diagnosis is made, so it's well worth checking for them if you can - hopefully, there are some things you can do to make him feel better for as long as possible, even though he's getting older.

First of all, you should get Zorro checked by your regular vet, as he has lost a lot of weight. Weight loss could be due to liver or kidney disease but it is also commonly seen in diabetes, hormonal disfunction or even tumors. Zorro should have a blood and urine test done first (and possibly abdominal scan and chest x-ray), and if the results are negative, you can think to increase the calories intake. Giving food for young, active/working dogs is one of the option. But if Zorro, for example suffers from diabetes, he will continue losing weight regardless what he is feed until the diabetes gets under control.

The weight loss and the not eating may indicate a disease state. At 12 years old, things like kidney disease and cancer become more worrisome. I recommend to have Stitch examined by the veterinarian and plan on running some diagnostics to go looking for any problems. Best of luck.

Hi there! It does sound like Trooper probably has some type of medical condition that is causing him to lose weight. There are many things that could cause this, so it's hard to say what might be wrong without being able to examine him and run some tests. Some common possibilities in addition to diabetes and cancer in older dogs would include chronic kidney or liver disease, or heart disease. I would recommend taking Trooper to the vet for an exam when you are able to. Your veterinarian can do blood work and x-rays if needed to help diagnose the cause of his weight loss and see what can be done to treat the problem.

He does indeed look overweight, my preferred range is hills metabolic as this promotes healthy weight loss whilst also preserving muscle mass and strength and is formulated to allow them to eat a reasonable volume of food so they do not feel hungry. Your vet tech can help you work out the correct amount to feed him and monitor closely for the first 6-8weeks, if he does not start to lose weight then blood tests to rule out hormonal conditions such as cushings, diabetes or thyroid disease may also be recommended
