help! what should i do for my dog's stinky breath?!?

There are few dog foods of worse quality than Beneful. Put your dog onto a better quality diet.

Take him to the vet. It needs to be established whether the dog has an intestinal issue or a dental problem. Clearly, you think it's a dental problem or you would not be considering tooth paste and a finger brush.

This is not going to go away on its own and there is nothing you can do at home, he needs a vet examination.

When was the last time you took Biggins to the vet for a Dental? You need to have his teeth cleaned at least twice a year by a vet to remove all the plaque and get rid of the bacteria. Store bought breath fresheners will do nothing, treats and bones won't do near enough. The smell coming from your dogs mouth could be caused by many things. He could have a Rotting tooth, an Infection and a bad odor from the mouth can also mean Liver and or Kidney Disease. You need to take your dog to the vet. The sooner you do it the better. If his breath smells that bad, he has an Infection and the Infection spreads and hits his bloodstream, he will become Septic and you can lose him. Part of the smell can also be coming from the Beneful you are feeding him. It's one of the worse and unhealthiest foods on the market. The ingredients that go into Commercial Dog Food like Beneful, Purina, Pedigree, Mighty Dog, Alpo, Iam's, Kibbles and bits and any dog food they sell in grocery stores or stores like Walmart, Walgreens, K-Mart. It you knew what ingredients are used to make foods like Beneful, it would disgust you and you would not longer want to feed it to your dog. I call commercial food Road Kill, which is exactly what it is. This is very detailed information about how they make commercial dog foods.

Take your dog to the vet and have his mouth checked out, before the situation gets any worse.

Since you said the vet has cleared him of medical and dental problems the usually cause bad breath, I'm guessing it is the VERY poor quality food you are giving him. I'm not trying to be critical, you probably just didn't know it was bad as most people ar not aware of these things. Go to dogfoodanalysis.com to see what would be better choices. You don't want to give him anything rated less than four stars. Were I you, I would start with a change in diet and brushing his teeth daily. If that doesn't help after about a month, talk to the vet again.

Brushing is the best thing for the dog. You need special toothpaste, avail in all pet stores. Start out by letting the dog taste/eat some from your finger. Your dog will give you a hard time at first. Do the best you can, try the front teeth to start.

good luck

Well, this is a problem among many dog-owners. My aunt's dog had the same problem. I would recommend treats that freshen up the dog's mouth, and if that doesn't work, you might consider a vet chech-up. Don't worry, it's probably nothing dangerous, just unpleasant.
