Can a dog be tested for Down syndrome?
No. Commercial canine genetic panels and veterinary diagnostic laboratories do not offer tests for Down syndrome because the disorder does not exist in dogs. Genetic testing for dogs screens for specific single-gene mutations, breed-related predispositions, and defined hereditary diseases like degenerative myelopathy or progressive retinal atrophy.
Why does my Boxer hold its tongue out and stare blankly?
A protruding tongue is usually the result of an abnormal jaw alignment, known as skeletal malocclusion, or an overlong tongue (macroglossia) relative to the compressed skull. Staring blankly, however, warrants clinical evaluation. It may indicate focal or absent seizures, sensory decline, or early signs of canine cognitive dysfunction if the dog is older.
What should I do if a puppy shows developmental delays?
Consult a licensed veterinarian immediately. Rather than assuming the puppy has a harmless developmental quirk, request complete blood chemistry, total T4 and TSH testing, and a thorough neurological exam to rule out congenital hypothyroidism, liver shunts, or hydrocephalus before irreversible damage occurs.
