I had a labrador/Great Dane mix that was indeed part of my soul, I still miss her. She only lived for ten years, but she was the best dog I have ever owned. HOWEVER, she hated water for the first seven years of her life. Refused to go swimming, or walk along the beach- (where the waves bring water up to 'get you') nothing to do with it. One COLD fall day, when she was seven years old, we were walking around the pond at the park. She spotted geese in the middle of the pond- and something in her head clicked, and she took off for the middle of the pond- yanked me right into the ice cold water- and she kept on going. Of course the geese just flew off and she swam back to me. She loved going swimming after that.
However, she never would go outside if it was raining. She would hold it all day long. If it was still raining in the evening, she would bolt out there, pee and run right back to the door.
The Golden we have now was afraid of the dark for his first year. Refused to leave the back door if it was dark. You had to walk out to the middle of the yard with him. If you didn't, he was NOT budging. Now he will go out in the dark, but if the grass is more than an inch tall, he does his business on the concrete drive. He only uses the driveway if the grass needs to be cut. Keep in mind, this is a HUNTING dog- trained to hunt geese. lol lol lol. He has NO problem running through brush- just wont use it to go potty.
AND my QUEEN Wiener dog- ha! So much as a sprinkle, and she isn't going outside. Gives me a dirty look that says, "Turn off the &^%$ sprinkler!".She will NOT Go out there. If I pick her up and put her out the door, she will camp out next to the door and not move until I let her in. She thinks anything on the floor (shoes, dirty clothes, papers the cat knocks off the table, etc) works great as a potty place- so I have to keep right on her. Give her a chance to wander off, then I have to go poop-hunting.
Dogs!
