Anxious to hear about Ava's diagnosis and treatment...and sorry to read Ava is losing her beautiful fur.
My 13-yr-old American Cocker has hypothyroidism and taking Levothyroxine. Before her diagnosis, she lost fur and had crusty patches on body (she had all the signs of Cushing's but test rendered negative).
Now, she has gained weight and is 50 lbs. (Her litter-mate has maintained a normal 38 lb.) So unknown what caused weight gain since she's taking thyroid med. daily.
All the best to both of you!
