It is said that it is purely the dogs breed and instinct that decides whether they will like water or not. Because Kahlua is a smaller breed, she tends to not like water where as a larger breed of dog would be more likely to like it. There are obviously some exceptions to that rule of thumb. When smaller dogs are in a bath, they feel like they are being submerged in water, so they feel like they might drown. This is why some dogs will start shivering and try to get out of the bath, because they don't want to drown.

Kahlua is very weird when it comes to getting cold and wet. She will not go near the bath and she will also steer clear from the pool, but when it snows out she will want to be outside all of the time. My dog absolutely loves the snow, but I cannot figure out why. It is cold and wet, just like in the bath, but she loves to play in the snow and get covered in it! If only she could talk and explain to me her reasoning...
We now take Kahlua to the doggy spa (groomer)
about every 4 weeks to keep up on her personal hygiene. We used to do all of that for her, but she would not come near us afterwords like she was holding a grudge against us. We have to drag her in through the spa doors, but in the end it is completely worth is to see her all clean and pretty and happy to see us when she is done.
I have come to the conclusion that if it were up to Kahlua, she would rather stay dirty and stinky than be bathed and clean.
