OK - another day.  Had a fine morning with Jack... all was well.  He had a pretty active morning.  Started struggling a bit more w/ breathing.  I called my doc - spoke w/ her - she told me to sit tight.  So I am.  Gave her the clincal signs I was seeing - she still told me to sit tight.  So, here I am.  Sitting tight.  He just went outside, peed and pooped, clear across the yard of course.... hopped back....now having some trouble catching his breath.  To be expected.  Soooooo -- just needed to type this out.  Oh and she has heard of the metronomic protocol and said there are pretty much no side effects.  So, if we make it to Monday, we may consider it.  So, even w/ my call, telling her of his change in breathing, she is talking about treatment options.... and, she is one of those straight forward type vets - no sugar coating.  If she was concerned, she'd tell me to bring him in.  She didn't, so I am trying to calm myself so he in turn will calm down.  Rollercoaster.
