Hello I’ve have a 15 month old cocker spaniel ever since we’ve had him he has always been a itchy dog .ive tried a lot of shampoos and also he’s in a expensive flea and worm tablet which I don’t think is helping . Also my dog is forever licking and chewing his paws I can’t get him to stop . He’s also on tablets for this as well which are not helping him . I’m so frustrated for him as this has been going on for ages . Can any help please ?
