Reasons for severe drooling in golden retrievers:
1. When the weather is hot in summer, dogs will dissipate heat through their tongues and secrete more saliva.
2. After a dog exercises strenuously, it will open its mouth wide and stick out its tongue to dissipate heat, which will cause serious drooling.
3. When a dog suffers from oral diseases, it will also drool seriously. You should take the dog to the pet hospital for treatment in time.
4. Dogs are greedy and will secrete a lot of saliva after being stimulated by food. This is normal.
5. If the dog is stuck by a foreign object, it will also drool a lot. The owner should remove the foreign object in time.
