as the dog i show is 3 and docked if i wanted to show her abroad in euro counties would i be able to? also HELP she is getting yellow staining on her white feathers under her tummy is there anything that will help remove it

Each country has it's own rules about docked dogs being shown, some countries have a (pardon the pun) cut off date after which no docked dog born after that date maybe shown - like here. Some state that if the dog was legally docked in the country of birth then it can still be shown, some say no docked dogs at all. So best to check with each country you are thinking of showing in.

My white dog pees up himself, he gets regular baths and lots of conditioner on those areas to keep the hair in good condition.

I dont know about the docking, but I keep afghans, and the boy gets pee on his coat. I have found that If I apply a paste of bicarbonate of soda and water to the fur for a few hours before bathing, that it takes out the yellow stains.
