The beginning of a new life - Zed's story

So the introduction of Esa to “Frank” went well and he came home with us on Sunday. Zed tested the waters when he got to our house – ie, he peed in the house. We immediately took him outside and when he came back in, he could tell he was in trouble – his ears were back and tail between his legs. Of course, about an hour or so after we brought Zed home, Dan had to go to work so it was me and the pups for the evening. 
That evening, Zed would not let me leave his sight. I did figure out that he knew “on your bed”. I pulled out one of Esa’s old beds (that she had torn a hole in) and he loves it. Whenever he thinks he’s in trouble, he heads for a bed (his or Esa’s). He’s a smarty – I went downstairs to get the laundry and told him stay (on his bed). Next thing I know, he’s down the stairs and I say “what are you doing?” and he goes running back upstairs. When I came upstairs, where is he, but on his bed!
Wednesday was Zed’s vet visit. My suspensions of Zed being something besides a Chihuahua mix and less than 10 years old were confirmed. Chrissy, our friend and vet from Companion Paws, believes he probably is more Jack Russell Terrier than Chihuahua, with everything else mixed in! As for the 10 years old, unless he has had a lot of dental work lately, he is probably more 6 years old than 10 years.
Zed has a VERY bad yeast infection – almost every other day he stinks. The treatment is topical unless it doesn’t get better and then it will be an anti-fungal medication. He has ear drops, mediated shampoo & conditional (2x a wk), and ear wash. So far so good - He has been itching less. We can also use Benadryl 2x a day also if needed. His blood work was good so if the topical meds don’t work, it’s the anti-fungal. He’s really good at letting me put the drops into his ears.
Zed is beginning to learn the schedule and is warming up to Esa. All Esa wants is for Zed to play with her. Of course Zed didn’t know what to think when Esa took her paw and slapped him! He growled at her. Zed gets overly excited when the leash comes out. For the last couple of days, he has learned that he needs to sit and wait when it is time for a walk.
We gave him his first bath on Wednesday after his doctor’s appointment and he did wonderful. Today was his second bath including an ear wash and he did great again.
Zed did play with Esa a little yesterday when Dan was outside with them. As soon as I pulled out the camera though, forget it. He was more interested in me.
