What’s one of the first things dogs do when they meet other dogs? That’s right! They sniff the other dog’s behind! Most dogs are not shy about getting to know other dogs and people. But you never really know what illnesses they might have. As dogs age, their immune systems become less resilient. Here are six ways to help boost your aging dog’s immune system so he can be as friendly as he likes!

1. Eat Nutritiously

A dog’s gastrointestinal tract is home to 65% of their immune cells, which means that diet and immunity are very closely intertwined. A diet full of nutrients is essential to maintaining your dog’s immune system. And they may need more key nutrients, like vitamins, minerals and protein, as they age.  

2. Get Moving

Getting outside for regular exercise and fresh air is one of the best things you can do for your dog. As well as releasing endorphins, exercise stimulates the lymphatic system, allowing the body to properly filter toxins. Exercise also relieves stress, which is good because stress negatively affects the immune system. So, grab the leash and some treats and explore the great outdoors.

3. Stay Trim

Talk to your vet about your dog’s ideal weight and how many calories they should consume each day to help keep them within a consistent, healthy range. Being overweight can put added strain on your dog’s immune system.

4. Put Hands to Fur

One of the easiest ways to help boost your dog’s immune system is to give them a massage by gently kneading their fur and rubbing their muscles. Massage stimulates the dog’s lymphatic system, and the relaxing time spent petting your pup benefits you, too!

5. Have a Change of Scenery

New sights, new smells and new sounds are important to dogs and humans alike. They keep us interested and excited about life. So, change your scenery once in a while by doing something new. Take a hike, go for a walk in the woods or visit a friend. Socializing your dog will keep their mind and body active.

6. Keep Toys Clean

The toys and bowls your dog uses every day can be hotbeds of bacteria. Daily washing of these items with warm water can help get rid of germs (but avoid dish soap because it could be toxic). Also, be sure to thoroughly dry toys and bowls after washing, as bacteria can grow on anything left damp.
