Don't ever try to stop a 135lbs. Great dane who is going after a 10 lb cat...by throwing up you leg! Ouch! I thought he just sprained it {if that is possiable!HA!} But the next morning I woke up SOAR AND BLACK AN BLUE! So I'm guessing he broke some blood vains! I'm lucky he didn't brake my leg! He's such a good boy! I really hope he is okay! Our vet cried when she heard the heart problem! She is such a GREAT VET!!
