Giving your pooch a nibble from your lunch or dinner may be common practice in your house, but some things are best left devoured by your pup, including dairy. Resist the urge to give in to those longing eyes, even if he combines them with that irresistible head tilt, when you're consuming anything made of milk.


Many dogs are lactose-intolerant due to not possessing enough lactase, or the enzyme that helps break down lactose. Spaniels and young puppies are commonly susceptible to the dangers of milk, but dogs can develop an intolerance for lactose as they grow. Dairy products are No. 2 on the VetInfo list of the six most common food allergies.


Your pup may not react right away, but symptoms of lactose intolerance or a milk allergy include loose stools and vomiting. Other gastrointestinal discomforts may result from intolerance. Weakness and skin rashes may also develop.
