Ok, so I took Tybalt in and he has demodex mites, the vet called it the red mange. Vet was a little worried about the demodex because it could mean Tybalt's immune system is a bit wonky since he isn't under any stress or anything that could suppress it. But hopefully it's more likely that the wonky immune system is just due to his hormones changing, he is right at that age where they start to transistion over to adult. That's the bad news.
Vet gave him a shot of ivermectin to jump start getting rid of the mites and also gave me Promeris to place on his skin and a two week course of anti-biotics.
I am also going to start him on his heartworm preventive after this course of medicine and the vet said the ivermectin in it will help contain any future flare ups if he has any. That's the good news.
Also, Tybalt's heart sounded good! Dr didn't note any murmurs and was very reassuring to me that he understood Cavaliers were high risk for MVD and that should be our top priority to look out for and gave me the numbers and address of the closest animal cardiologists (there are just a few in this area and pretty far away) and said at least once a year, I need to have Tybalt checked by one. Does that sound about right?
And the entire office just loved Tybalt. He slept almost the whole time, I kid you not. They couldn't get over it. He got passed around and loved on. He ate it up.
So yay! Nothing that can't be fixed with a little TLC.
