Weight gain in dogs often happens for the same reasons it does in people. Although disorders and diseases may trigger weight gain in some dogs, most animals gain weight due to poor diet, overeating, or a lack of exercise. Some of the possible causes of weight gain can include:
Cushing's disease
Dogs with
Cushing's disease have hormonal imbalances due to overactive pituitary or adrenal glands. If you notice your dog is developing a rounded abdomen, is panting and eating more, your vet may need to evaluate their hormone levels.
Genetic predisposition
Overeating and lack of exercise
Skipping walks and going
overboard on the kibble can cause a dog's waistline to expand, especially when they both occur at the same time. This particular cause of weight gain is easier to prevent than reverse.
Some dogs require more exercise than others due to differences in metabolism caused by genetics, age, medications, and medical history.
Medication
Some medications (like
phenobarbital and glucocorticoids) can cause woofers to pack on the pounds. Inform your veterinarian if your pet suddenly begins to pick up weight after starting a new drug. The vet may need to change the medication or lower the dosage.
Pregnancy
If your female dog happens to be unsterilized, weight gain could be a result of an unplanned
pregnancy. If Lady has recently gone through a heat cycle or had contact with intact males, you may want to schedule an examination.
Stress
Dogs with
high stress and
anxiety levels sometimes soothe themselves by eating and often consume more calories than they burn. Stress also increases cortisol levels, and when levels remain high for long periods, it can cause muscle loss and slow their metabolism.
Thyroid disease
Hypothyroidism is a common contributor to weight gain in canines. Schedule a vet appointment if your dog's weight gain is accompanied by
lethargy, a dull coat, or oily, greasy skin. The vet will probably want to run a complete blood count and biochemical profile to help detect any underlying conditions.
So when should you be worried about your dog's weight?
