Twice a week my son brings his 12-pound long-haired Poodle, Molly, who walks, jumps, and wrestles my 20-pound (less-energetic)Doxy-mix Sparky for hours. 1) About five times a day for ten-minute periods Sparky will stretch his body so that his nose is next to his anus and hold that position for 10 or more seconds. The postion is almost motionless. I have never seen him sniff or lick. I observed authentic animal expression of movement, body language, and timing. The animal communicated fear and a sense of unusual behavior to the point that I clearly perceived that a presence of wrongness was evident. 2) Also, on his back his bed pad just before midnight tonight I placed both hands under him from opposite sides so that I was able to place my right thumb next to my left little finger and right index finger almost into the crevice of my left wrist and the base of my left palm. Thus, on his back Sparky's completely relaxed 21 pounds sank into my relaxed masseur's hands. So slowly so be almost stopped, my finger tips sense his muscles on both sides of his spine and move them gently and slowly against and away from each other. He immediately stretches his front legs above his head and his rear legs below him as far as they will go and hold them 10 to 15 seconds. His eyes glazed over he relaxes while I continue to massage and then he does the long stretch/hold and relax two more times. 1. Are the anal freeze and the massage freeze early symptoms of back injuries and disease? 2. What should I do now? Keep Molly away for two weeks? Stop Sparky from all jumping? Massage and date/time record all changes in reactions to massage and "anal stretches"? Go to the vet? ??? P.S At 3 1/2 Sparky's (Doxy mix) front legs are almost "S" curved. Should I worry? Do something? What? RSVP Thank you very much!!!
