Can dogs drink milk?
Dogs produce little lactase, so milk can cause diarrhea and digestive upset (ASPCA). AKC says dogs can have milk, but tolerance varies.
How to serve it: a small sip at most; fresh water stays the main drink
Questions
Can cats drink milk?
Better not. Many cats are lactose-intolerant; cow's, sheep's or goat's milk can cause diarrhea. Cornell advises against milk as a treat (Cornell, iCatCare, ASPCA).
