There may be several reasons why dogs like the smell of aquatic plants. First of all, dogs naturally like to explore and smell new smells, including the smell of plants. Secondly, aquatic plants may contain some ingredients or chemicals that dogs like, which can stimulate their taste and smell, thereby arousing their interest. In addition, some dogs may like the taste of aquatic plants because their ancestors are wolves. Wolves may eat some plants in the natural environment. The taste of aquatic plants may be familiar and natural to dogs.
It should be noted that although dogs may like the taste of waterweed, it does not mean that waterweed is suitable food for dogs. Some aquatic plants may contain toxins or chemicals, and some may even be harmful to dogs. Therefore, it is recommended that owners do not let their dogs eat grass freely, especially if they do not know the source and quality of the grass. If your dog has digestive problems or other symptoms of discomfort, seek medical attention promptly.
