Lactose intolerant dogs cannot drink

Lactose intolerant dogs lack lactase in their bodies and cannot break down the lactose in milk. Lactose cannot be converted into galactose and glucose for absorption and utilization in the small intestine. Instead, it directly enters the large intestine, which increases the osmotic pressure of the intestinal cavity and causes the large intestinal mucosa to absorb a large amount of water. Bacterial fermentation of lactose in the intestine can produce lactic acid, which can stimulate the large intestine and cause symptoms such as bloating, abdominal pain, gas and diarrhea.

Dogs allergic to milk cannot drink it

This situation is usually in the minority, but there are cases where milk allergy may cause a threat to the dog’s life. This kind of dog should never be fed milk.

Dogs cannot drink after surgery

After surgery, the lactase in the dog’s body will be affected and reduced. After drinking milk, lactose cannot be decomposed and will ferment in the body, producing Water, lactic acid and large amounts of carbon dioxide cause abdominal distension in dogs. During abdominal surgery, the intestinal tube is exposed to the air for a long time, and the mesentery is stretched, which delays the recovery of intestinal peristalsis after surgery. The gas produced in the intestinal cavity due to swallowing or fermentation cannot be discharged in time, which will aggravate abdominal distension and may cause abdominal pain, intra-abdominal The pressure increases, and the sutures may even bulge and crack, and the abdominal wall incision may split.
