Folks, good news finally. Thank you for all the kind wishes for Frodo's good health.
The vet said that this was a case of severe gastroenteristis which also caused acute cramping on which account he was unable to get himself up. With some medicines for his stomach ailment and glucose and digestive medicines, Frodo recovered slowly but steadily and is now back to his bouncy happy self. He is now walking and running fine and touch wood will stay that way. Thanks again.....
Incidentally my basset who was also worried and missing his playtime with Frodo is back to troubling the lab as usual and they are keeping each other and us occupied with antics through the day. Ciao
