yep- the towel trick works wonders.
Be very careful with spot treatment. Our (late) dog Gatsby was treated by the vet as part of the European passport return to UK trip- and she applied it wrongly and it went all over her coat, instead of on a skin area behind the neck. We then travelled all the way to our flat in the Midlands and the next day she was sick and couldn't eat. After a few days we took her to the vet who thought she had throat cancer. She had to give her a full anesthetic to examine her properly- and found her mouth and throat were VERY badly ulcerated- and asked if she had had access to strong chemicals, bleach, etc. We said NO, but then realised what had happened. The French vet refused totally to take any responsibility- so I contacted the Pharmaceutical company who agreed it was the cause, and that the vet was totally responsible. The poor dog suffered for weeks- it cost us a fortune, and the French vet refused to participate- even when contacted by the Pharma company. We now live in the area and make sure we tell anyone who asks NOT to go to him!
