In July, my family and I adopted an orphaned puppy who’s mom had been hit by a car. His name is Rudy, and he’s a now six month old Texas Heeler (Australian Shepherd/Red Heeler). He’s a very smart pup, as both of his parents are two of the smartest breeds of dogs out there. He figured out the whole house training thing fairly quickly, although it was a struggle in the beginning. For months now, he’s been going outside to use the bathroom and even lets us know he needs to go out by ringing a bell that’s attached to the doorknob of our front door. He’s had no accidents since then, until recently. He’s been peeing and pooping in the house at least once a day, but his schedule hasn’t changed at all! He usually rings the bell when he needs to go, and he hasn’t been doing that! Just squats and goes. It’s becoming really frustrating for my family. Today, he peed in the floor three separate times! Not even a warning! Please help!
