please can someone advise me , went to the caravan Friday as we do every weekend with Ronnie , where she goes on the beach , she was fine on Saturday morning , but having spent a good part of the day on the beach , on the night i noticed she was licking herself alot down below , and also not drinking any water (which she normally drinks tons ) . now since Saturday night she is going for a wee constantly only to wee a little bit . and also she did have some discharge in her wee Sunday morning but no more. i am so worried can anyone advise me to what this might be please . could it be cystitus ? what can i giver her to help her ? i have been giving her small amounts of nat yogurt . is there anything else i should do , or should i just get her to the vets ? oh forgot to say she is a 3 month old gsd .

thank you . i do hope someone comes along soon
