Our lab, Lil Spanky, has developed an itch this past week, and I know it must be making her crazy because her scratching is driving us nuts. I've looked her over very closely, and haven't been able to find any kinds of creepy crawlies like fleas or ticks or anything, plus we use Advantix regularly, and it works great. I did find some red irritated areas, where she's been biting and diggin tho. At first I suspected mosquito bites, as they were really fierce around here just before the weather changed. And I know that she did run through an area where there is some poison ivy. But that all was about 2 weeks ago. I gave her some Benadryl a while ago, and she seems to be getting some rest right now. Got any ideas?
