Thank you for raising this important topic. There is another article here
about Cutaneous and Renal Glomerular Vasculopathy (CRGV) that might be of interest to members. Unfortunately it doesn't take us much further in efforts to prevent our dogs from being infected. On the subject of how it can be avoided, they say:"As we don’t know the exact cause, avoidance is difficult. However, thorough washing of your dog’s coat after walking in woodland (especially if muddy… like everywhere this year!) is a sensible precaution that should reduce the risk. In addition, it is likely that certain places pose a higher risk than others; if there has been a case in your area, it is probably wise to avoid areas where the affected dog(s) were walked in the days before they were diagnosed. It’s also really important to check your dogs over regularly – not just for sores or ulcers, but also for cuts, ticks, mats of hair or other injuries."
Having discussed the matter on another forum, one of our members who lives in the country has started to wash her dogs' legs and feet after walking. She uses dilute Hibiscrub. It is a simple thing to do and perhaps may be a good thing to do after walking in woodland or muddy areas.
