Hi CL, so pleased to hear about the swimming, made me think I may go back. I just find it so hard and suffer cramps when everyone else seems to glide effortless through the water.
Do try the garlic for a start it is a cheap natural remedy but garlic is also good for the dog just like it is for humans. Remember the few you see are the tip of the iceburg, they soon lay eggs in your carpets etc. Don't try one of those collars tho, one of my dogs was very poorly after using one. have a good week end.
