In the wild, dogs spend a lot of their time chewing on bones, carcasses, sticks and kernels. For example, Australian dingoes can feed for up to 108 minutes in a single session .
But most domestic dogs chew far less than their free-roaming counterparts. This is largely because of the introduction of easy-to-eat, processed pet foods such as kibble, which now comprises the majority of domestic dogs’ diet .
This is a problem because although chewing carries some risks, overall it has significant benefits for dogs.
As our new review , published in Frontiers in Veterinary Science, demonstrates, it enriches the physical, psychological and emotional health of dogs in many interconnected ways. 1. Food acquisition and nourishment
Dogs chew primarily to nourish themselves.
Their large canine, premolar and molar teeth and wide gape help them to capture and dismember prey. Chewing whole carcasses provides them access to marrow, fibre and minerals that would otherwise be inaccessible.
When they are not chowing down on body parts, free-ranging dogs forage on nuts, berries, and insects – a portion of which are also hidden in kernels, shells or exoskeletons and require chewing. Wild dogs such as dingoes can feed for up to 108 minutes in a single session. 2. Clean teeth and oral hygiene
Dental disease is one of the most common health issues in companion and kennelled dogs . It is more common in smaller and older dogs.
The abrasive action of chewing on hard and fibrous materials helps to remove and prevent the formation of plaque.This reduces bad breath, gum disease, tooth loss and therefore the requirement for dental procedures at the vet clinic.Of course, dogs with existing dental issues might find it impossible to chew. And it is recognised that some dental fractures may arise from chewing. 3. Gastrointestinal health Chewing between meals can help facilitate digestion in all mammals.It can also prevent stomach inflammation and stimulate peristalsis (waves of contractions) in the gastrointestinal tract.This helps maintain regular bowel movements and stool consistency . 4. Healthy microbiome The action of chewing promotes resident bugs that comprise a healthy microbiome and reduces harmful microbes, both in […]
