A husky who loses weight without any obvious cause should be evaluated by a vet. If your husky is showing signs of weakness or lethargy, then it’s likely that something else is wrong. As mentioned before, there are many different illnesses that can cause your husky to lose weight. These illnesses can range from mild to severe and can have varying symptoms depending on the disease. The first thing you should do when your husky loses weight is contact your veterinarian. They will perform a physical examination and provide a thorough health history. During this visit, they may also recommend bloodwork to determine if your husky has any underlying issues. Depending on the results of the bloodwork, the doctor may recommend further tests such as diagnostic imaging, a biopsy, or an ultrasound. These exams will allow your veterinarian to determine whether or not your husky is suffering from one of the many possible conditions that can lead to weight loss in huskies. If your husky needs further testing, then you will want to make an appointment with your vet so that they can evaluate your husky.
