  1. Hi All
    My 13 years old Bichon has just been doagnosed with ME, he sometimes regurgitates before but it has became more serious in the past week. Does ME become more serious with age? thanks for your advise as I am new to this and am overwhelmed!

    1. Hi Elaine,
      It is overwhelming to get the diagnosis. When ME comes on all of sudden be sure to have your guy checked for a possible primary disease such as myasthenia gravis, hypothyroidism and Addison Disease. Many times no specific cause can be found and it is deemed idiopathic (no known cause) but it can be managed successfully no matter what. Be sure to feed upright and keep your pup in an upright position for 15-20 minutes, some need more time, some less. Find the right consistency of food. Some do better with little meatballs, others with a slurry. Get a neck hug for at night. This helps saliva drain down when they are laying down to sleep or rest. Please join the facebook groups. Loads of important information and clever ideas on how to manage!
