Changes in Dog Weight

Weight loss and chronic disease in dogs is a pet owner’s worst nightmare. The signs can appear very quickly in a pet. There are a variety of causes, so it’s best to have the pet checked out by a veterinarian as soon as possible. Time can be very crucial to the health of the pet, so it’s best to get a medical opinion. 

There can be many causes of weight loss in a dog, such as poor diet or reduced appetite, but more serious causes will be determined by the veterinarian. The major sign for pet owners to be aware of is a 10 % weight loss, which is rapid and noticeable. Other signs are low energy levels in the pet, lethargy or sleeping more, or the pet loses hair or their coat is dull. 

A veterinarian will conduct a physical examination and will require a blood count and urinalysis to determine if parasites, such as heartworm or intestinal worms, can factor into the weight loss. These lab tests can also determine if infections, either viral, bacterial or fungal, can be causing the weight loss. Depending on the lab results, the veterinarian may take x-rays to rule-out bowel obstructions or other organ diseases or failures. Exploratory surgery may be necessary to determine any blockages. If the pet has ingested harmful chemicals or toxins, the veterinarian can recommend immediate treatment procedures. Senior pets can experience reduced appetites that will cause weight loss. Any weight loss in an older animal should be evaluated by a veterinarian. 

Chronic diseases such as diabetes, cancer or dental problems can cause weight loss in animals. Treatment will depend on the cause of the weight loss. Dental disease can impede eating due to pain so treatment can provide relief and appetite will return. Appetite stimulants may be necessary to encourage the dog to eat. In extreme cases, force-feeding (intravenous) may be necessary. Depression or other behavior issues can cause weight loss in dogs. A change in family dynamic, loss of home or owners, can cause a pet to lose their appetite and will incur weight loss. 

Pet parents can provide treatment at home by charting food and water intake. Also, providing a high-quality diet would be recommended. Frequently weighing the pet will also provide the pet parent with a current basis of how their pet is improving or declining. Pet parents should use lots of positive reinforcement and provide safe areas for their pets to ensure a quick recovery for their pets.
