Can dogs eat milk?
CAUTION Category: Dairy · Reviewed September 2026
Puppies digest their mother's milk fine, but most adult dogs produce little lactase, so a saucer of milk often leads to gas, loose stools and stomach pain within hours. A few laps from a cereal bowl is rarely worse than smelly; a full bowl is a different story. Lactose-free dog milk products exist if your dog loves dairy.
Symptoms to watch for
- diarrhea
- gas
- abdominal discomfort
- vomiting
If you suspect poisoning: call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 (available 24/7). Do not induce vomiting unless instructed by a professional.
