My sister just got a border collie X cattle dog cross. She asked what she should give as heart worm preventitive ( as she's not real trusting of the vets in her qurkey little town.. hehe) She looked online but gets conflicting opinions.
Anyone with this breed mix or have had either breed? What could you use....... Thank you for any advice.
