4 Reasons Why Dogs Are Good for Your Health

One of the things I love about writing blogs is that I get to talk about stuff that’s relevant in my life, where I’ve been inspired, had a wise insight, or learned something new.

I’ve written a few blogs about my dog Oscar and what I’ve learned from him. If you haven’t been keeping up to date, he’s a yellow (golden) Labrador retriever and he’s 11 and a half months old (that’s him in the photo!).

We moved house a few weeks ago and now live in the country (in a beautiful village called Bridge of Allan, in central Scotland). I’m so enjoying the long healthy walks. I say healthy, because I feel healthy with all the miles I walk, breathing in the fresh country air. It got me thinking that dogs really are incredibly healthy for us.

Here’s 4 reasons why:

1) Dogs boost your immune system

Many people find that when they first get a dog they get much fewer colds. The main reason for this is that dogs (and puppies) bring dirt into the house on their paws. The dirt contains tiny bacteria that gives our immune systems something to work on. Like muscles, the immune system needs to work to build its strength.

Living in too clean an environment can lessen the immune system. It’s one of the suggested scientific reasons for an increase in allergies over the past few decades.

When a dog brings dirt into the house on it’s paws the human immune systems go to work, building up its muscles like we’ve gone to the ‘immune system gym’. As this happens, the immune system becomes more robust and resilient, and we’re more protected from colds and other illnesses and diseases.

2) The give us plenty of exercise

I walk about 20 miles a week with Oscar. I’ve lost about 8 pounds in weight since he came into our lives. Last weekend I ran the ‘Perth Kilt Run’, which is a 5k run in Perth (Scotland) and you have to wear a kilt. I ran a rather respectable 24 minutes and 39 seconds, which I think is good considering I hadn’t done any running training and a kilt gets quite heavy after about 4k  .

I’m certain that walking all those miles with Oscar was excellent training for me.

3) They’re good for the heart

Research shows that interacting with dogs elevates levels of the hormone, oxytocin. As well as it’s role in childbirth and breast feeding (oxytocin is involved in the ‘letting down’ response of breast milk), oxytocin is a powerful ‘cardioprotective’ hormone (it protects the heart and cardiovascular system). Research shows that it lowers blood pressure and significantly reduces levels of free radicals and inflammation, two families of chemicals involved in cardiovascular disease.

Couple this with a stronger immune system and more exercise, it’s why research also shows that the chances of a second heart attack, for men who had one previously, is 400% lower for men who have a dog compared with men who don’t.

4) They’re good for mental health

We’re a social species. Humans need social contact. It’s built into our genome and is why we’re healthier and live longer when we connect with each other. Social network research shows that we’re healthier the more connected we are.

Part of this reason is, of course, oxytocin. Dogs are great company and we bond strongly with them. It’s not at all uncommon for people to talk to their dogs. I know! I talk to Oscar and tell him what I’m up to. 

Human and animal contact also helps counter stress and is protective towards depression, so having a dog is also good for our mental health. Of course, we can also say the same for cats (in case you’re a cat owner reading this and are wondering). 

So overall, I think it’s nice to reflect on how dogs are so good for our health and to feel deep gratitude for their presence in our lives. I feel immensely grateful for Oscar’s presence. He has changed my life for the better on so many levels.
