I would like to thank Your Vet Online for the helpful advice provided to me in respect of my gorgeous horse Rosemount Prince who was suffering from an acute case of lice . I had been treating it topically but it was the advice re the appropriate internal drench which has helped him turn the corner . A number of friends, know how bad this lice infestation was – his paddock mates don’t have them but this very special horse just plummeted downhill quickly . He is quite enjoying being an invalid in the quarantine paddock but it’s good to see him improving ! Many thanks again.
