Estrus, or heat, is the stage in a female dog's reproductive cycle during which she becomes receptive to mating with males. At this time, estrogen levels first increase and then sharply decrease, and mature eggs are released from the ovaries. Ideally, your dog should be spayed before she enters her first heat cycle.
Injury, stroke, poisoning, and infections can all cause your dog to lose its balance. Because these things can be dangerous or even life threatening, call your vet immediately if your dog is falling down.
Dog Loss of Balance: Common Causes and Treatments
A few of the more common causes of falling down in dogs include:
Vestibular Syndrome. Vestibular syndrome is caused by dysfunction of the inner ear. Because the symptoms occur suddenly, they are sometimes confused with symptoms of stroke. Along with loss of balance and falling over, signs may include head tilt, walking in circles, vomiting, nausea, and flicking of the eyes from side to side.
Treating vestibular syndrome depends on the cause. Many dogs need support for secondary symptoms such as nausea, vomiting, and dehydration.
Ear Infection. Inner ear infections are a common cause of dogs losing their balance. Other symptoms include head shaking and scratching, eye flicking, walking in circles. Often there may be redness, swelling, discharge, and odor associated with the affected ear.
Left untreated, infections of the external parts of the ear can move deeper, become more serious, and lead to complications like inner ear infection or meningitis. So always have your dog seen by a veterinarian if you suspect an ear infection. Treating ear infections may include a professional cleaning, topical medications, antibiotics, anti-inflammatories, and possibly surgery for chronic or serious infections.
Injury. Injuries such as head trauma or damage to the inner ear can cause dogs to lose their balance. Your dog can't tell you when it's in pain, and dogs sometimes mask hurt with behaviors such as wagging their tail. So it's important to be aware of canine signs of pain. They include slower reflexes, heavy panting, biting or licking the wounded area, anxiety, enlarged pupils, reluctance to lie down, and change in appetite.
