Well..my daughters golden retriever had a huge mass removed..his stitches didn't hold..so they put in staples..I was so afraid it would hurt him..but he was fine! No pain! Sounds nasty..I know! Yay for sweet Chaos...Ummm..Jake was NEVER much of a hum per..but he seems wilder than ever! He is flying all over my house...all the time. Maybe they missed a ball!
