We do not use heartworm medication, flea or tick.  We use alternative preventative options.  
We do not believe adding more toxins to our dogs body helps them.  It actually weakens their immune system.
 Instead we build up their immune system naturally.
We have our dogs tested for heartworm.  They have never had heartworm, even our almost 9 year old livestock guardian dogs.  
Please ask if interested in knowing more.
......more to be added soon!......
