Are you looking for solutions to your pet's health problems in a bottle?
If so, you are barking up the wrong tree. You will not find health in a bottle, jar or packet. Natural or otherwise.
Health can only EVER be built by an appropriate lifestyle...species appropriate foods, pure clean water, exercise, mental stimulation, fresh air & sunshine, adequate rest and minimizing exposure to chemicals & carcinogens.
Just like prescription drugs, many natural supplements only suppress symptoms. Supplements and remedies can be used to support the animal in it's healing efforts. After all it is the actual organism - when it has all the resources it needs that will heal itself. Healing comes from within. This is the way nature has designed all living creatures...with an intrinsic ability to heal.
External influences can either assist or hinder the bodies ability to heal.
First things first, make sure your animal's lifestyle is appropriate for their species. Second, give supplements that will support that animal's individual needs if necessary.
