My sister-in-law has a 3 year old Dobie bitch and has just emailed me this... "Took Molly to vets on Friday as she's been coming out in spots, on Friday there were dozens of them ... I knew she didn't have fleas but thought I should take her. Vet said it was probably an allergic reaction to something, anyway gave her an injection and some pills and a bath. Saturday morning all spots had virtually gone. Went out Saturday night, came home, went upstairs, her bed was wet through. Put throw on our bed and let her sleep on that, woke up was like someone had thrown a bucket of water on the bed. Washed bedding, bought new quilt, everytime she got up from wherever she was laid there was a massive wet patch. Went to bed last night, had to get up at 2am this morning to change her bed as it was wet through again (she woke me up as if to say "me beds all wet" ... Bless. So changed the bed, got up this morning, bed wet through again. Was gonna take her back to vets today but been home at lunch time and it's all dry, so I have no idea what that was all about." Any ideas?
