The six main types of dog enrichment include physical enrichment, such as all sorts of activities requiring physical effort. Mental or cognitive enrichment methods include anything that require your pup to put their brain into work mode. Social enrichment means that a dog has plenty of opportunities to socialize with people of all ages, other dogs, and even other animals. Then there is also oral enrichment, smell based enrichment, and nutritional enrichment. Since dogs have heightened senses when it comes to smell and taste, it's crucial to provide them with plenty of enrichment in those areas as well.
