Why did my dog attack my other dog they are not aggressive? General Dog Discussions
Last night my 3year old Lab/ Blue Heeler mix attacked my 1 year old Chihuahua. They were outside for like 20 mins and then I heard yelping so I ran out there and they both had blood all over themselves. They weren't injured badly, but what could have caused this to happen? We have had no problems with them before this they are buddies always playing together and sleeping together.They are both females and spayed. I also noticed today that my older dog keeps sniffing my younger one especially her private area.
