Apparently another home remedy for canine bladder infections is cream of tartar. We have heard that this really helps, but haven't tried it yet. Apparently, you mix a teaspoon of cream of tartar in the water bowl every day for about a week .
If the home remedies don't start working right away, please see your Vet asap.

1. Use baking soda as a dry wash for your dogs. Sprinkle on, rub in and brush out. This is an easy way to control odor between bathing.
2. Maintain healthy teeth by dipping a damp, soft toothbrush in baking soda and brush gently. To help with bad breath try using the following solution mixed in a spray bottle. Dissolve 1/2 teaspoon of salt and 1/2 teaspoon of baking soda in 1 cup of water. Spray your pet’s mouth regularly.

If anyone knows more info, please let us know. :)
