Also, you want to make sure they get enough time to play and have fun as well as taking them for daily walks and runs to make sure they get good cardiovascular exercise.
Outside of that, there are numerous pet health products you can buy to maintain a healthy body for them. For example, you might want to pick up some dog eye drops or tear stain removers to make sure they have good vision and don't get cataracts.

You always want to maintain good dog eye health if you can. You also want to make sure you clean their teeth daily if possible. Their gums should never bleed.
You don't want your dog going deaf, do you? Make sure to buy some good animal health products that help keep their ears clean and clear of any wax buildup.
Then there's the flea and tick issue. Many dogs can have this problem and it must be a nightmare for them and there is nothing they can do about it.
They must rely on you to help them. Imagine if you had a head full of fleas biting you all day. Then you can be proactive and purchase some dog supplements and vitamins to make sure they get all the vitamins, minerals, and nutrients they need to support a long and healthy life.
