Can dogs drink milk then or is it something that should be scraped off the list of things dogs can eat? Of course, milk is not a toxin and therefore you won’t find it on the list of products poisonous to dogs, but it can cause enough problems to top the list as one of those thing to avoid giving to puppies and dogs. Other than diarrhea and flatulence, in some dogs, cow’s milk can cause also cramps and nausea. Symptoms of lactose intolerance in dogs can be seen as early as 30 to 120 minutes after ingesting milk or a dairy product that contains lactose, explains board-certified veterinary nutritionist, Dr. Rebecca Remillard.
Are Dogs Lactose Intolerant?

Not many people know that dogs are actually lactose intolerant. If you’re lactose intolerant, you know that consuming dairy causes gas, diarrhea, rashes, and painful bloating when you consume it. Dogs have a very similar reaction when they’re given regular or large servings of milk. Not many dogs will turn down the opportunity for the leftover milk in your cereal bowl or some cheese, but they can’t understand the havoc it’s going to wreck in their digestive system. Most dogs don’t have lactose intolerance problems, so I don’t even consider it until it proves to be a problem.

You may be tempted to feed your dog milk, especially when he's a puppy. However, many dogs suffer from lactose intolerance, so it is better if you avoid giving your dog milk. If your dog has no allergic reactions or intolerances, you can feed him milk.The problem with dairy is all dogs aren’t lactose intolerant, but if they are, they don’t have the ability to digest dairy like humans do. They don’t naturally produce lactase, which is an enzyme necessary for breaking down lactose, the sugar found in milk.The reason why you should not feed your dog milk is the fact that it may contain lactose, and many dogs have allergic reactions to this substance. The symptoms of lactose intolerance or allergies will include:For instance, cheese could trigger lactose intolerance for some dogs. It triggers them to strain while defecating and produce little, difficult, dry feces. Lots of dog owners are supplementing their pet’s diet plan with yogurt or cheese without any adverse effects.Puppies can drink their mothers’ milk and can digest all of the proteins, sugars, and enzymes in that milk quite well. However, as a puppy gets older and stops drinking its mother’s milk, the puppy may also lose its ability to digest lactose, a milk sugar, leading to lactose intolerance, which is just like the lactose intolerance some humans can have. Not all dogs grow up to be lactose-intolerant, though. This means you essentially have to test how your dog handles small amounts of dairy products like milk and cream.Milk can be given to dogs from time to time as a treat, but it is not a necessity in their diet.  Something to keep in mind though is the fact that some pets cannot tolerate milk because they do not produce the enzyme known as lactase which helps with the digestion of lactose (a sugar found in milk.) For pets that can tolerate milk, it is a good source of protein and calcium. However after weaning, the level of lactase activity falls to about ten percent of its peak activity. If more lactose is consumed than what the animal can digest, diarrhea will often occur, this is whats known as lactose intolerance. If a person suspects that their dog is lactose intolerant, limiting or eliminating dairy products from their diet is the smartest thing to do.
