Excellent post...and exactly why I say "yes, please talk to others about health issues". So many Cavalier owners aren't aware of SM and MVD and it's up to us to educate and enlighten them. I am thankful I was aware of what SM is and what the signs are so that when I noticed odd behavior in my girl that it wasn't a "quirky" behavior (I didn't know about patellas when she was little and put her "funny little walk" down to a quirk, not realizing she had a bad knee) I knew I needed to have her looked at further.
I wish I had known before hand and I wouldn't have been hit with this blindsided...so to speak. I would have know earlier some of the signs acossiated with sm. Instead I shunned it all off as being quirks she has or her getting older
I think the key is not approach this in a "preachy" manner but rather in a way of sharing information.
So glad you were able to sort out what was going on with Sophia, get her on medication and improve her quality of life. Good for you. Please keep us updated on how she does. She looks like such a sweet girl.
