You guys are the best! Thank all of you for your helpful advice & well wishes.
I drug my butt home this afternoon, but I couldn't collapse right away. However, Riley sure did. He did well on the trip, but tired out very quickly each day. He always loves my parents' big back yard. He and the Atomic Chihuahua who owns my folks tolerate each other.
He goes for his 3rd chemo treatment tomorrow & is currently on prednisone which makes him an insatiable, ravenous beast! He usually has very good manners, but he tried to grab cheese off of the coffee table and yams off of the kitchen counter. Oh, so close...
Jeffery: I am wondering if your pugs had really soft stools on the Science Diet. (Gross question, but poop is very important stuff!) You are so right about the doctor. The oncologist is really kind & patient. She spends as much time with me as I need, and explains everything as we proceed. I haven't yet confronted her with the Tear Test because I try to be strong, and then spend half an hour bawling in the bathroom before I can make the drive home. I know that she will exceed my expectations when such a time arises. I feel very fortunate to have her treating Riley. The other oncologist at the hospital isn't nearly so gentle.
Lily: You are wise to remind me of Riley's age. Cavaliers are "supposed" to live to around 10 years or so, but my friend has several who are 13 or 14. So, I thought if I fed Riley well and kept him well-exercised, I could share my life with him longer. You just never know.
Susanne: Yes, yes, yes! Send whatever energy you feel like sending. I have been amazed at how well Riley responds to Donna's energy work. Animals don't let their brains get in the way like humans can, and so I believe that type of work is very beneficial to them. Wow, a sparrow??
Selene: I have saved the PDF file that you posted. Thank you so much. I will study the information that's on page 18, hopefully before Riley's appointment tomorrow. I, myself, use medical & alternative traditions to deal with my own malady and have found value in both.
I can't tell you how much I appreciate the time each of you spent on responding.

It's so hard to look at my little guy and get my head around "cancer." It just brings me to my knees. Our pets get to places we never even knew we had.
