If your dog forgets where the front door is or can’t seem to find his food bowl, take note. His confusion may be the first sign of a more serious condition. Confusion can occur suddenly or gradually, but either way, it’s disturbing for you and your dog.
Causes
Older dogs who gradually become disoriented may suffer from cognitive dysfunction syndrome, a newly recognized disease in dogs that resembles dementia in people. Slow-growing brain tumors also can cause confusion.
Sudden confusion can occur with a blow to the head, abnormal blood sugar levels (particularly low blood sugar), infections, seizures, or exposure to toxins, such as chemicals or spider bites. Household changes, such as guests staying in your home, also can throw your dog for a loop.
What you can do at home
If your older dog seems confused, now is not the time to rearrange your furniture or experiment with a new feeding schedule. Keep environmental changes to a minimum. Your pet may feel anxious, so provide extra love and reassurance.
When to call the veterinarian
Sudden confusion is a sign your dog needs immediate veterinary care. An examination is also a good idea for any pet exhibiting gradual signs of confusion. In older dogs, certain diseases can accelerate age-related changes, and your veterinarian will check for those conditions.
What your veterinarian will do
Your veterinarian will perform a complete examination, including a neurological assessment and possibly blood tests and X-rays. The doctor also may recommend more advanced diagnostic procedures, such as magnetic resonance imaging (MRI), to check for a brain tumor.
Treatment will vary, depending on the cause of confusion. A new medication called selegiline hydrochloride (or l-deprenyl) helps manage the signs of cognitive dysfunction syndrome in older dogs, improving their quality of life. Your veterinarian may prescribe a different behavior-modifying medication, depending on your dog’s symptoms.
The bottom line: If you see behavioral changes in your older dog, don’t assume they’re normal and unavoidable. Ask your veterinarian what you can do to keep your pet feeling and acting young.
