Recovery can be a rollercoaster

It has been 1 month and 1 day today and Boomer is moving slow.  He is licking his remaining back leg a lot and I have checked him several times in fear of another tumor popping up.  There is nothing.  By now I would like to think he is well on his way to being recovered.  Then, it faces me, he is 7+ years old and it is probably harder for him to recover than a younger pup.  It took him a lot of (heartbreaking) time to get up the 8 stairs to the kitchen but he still managed it before my hubby could stop him tonight.  I gave him some tramadol for his pain and hope he is doing better in the morning.  Maybe Boomer has just really overdone it today.   He jumped off of the bed twice and did the 15 stair climb upstairs 3 times not to count coming up 8 stairs 4 or 5 times today.  But, he ate dinner downstairs in the entrance room tonight because he didn’t want to do those 8 stairs.  (He had been eating with the rest of the pack both in the morning and evening for the past week.)  Sometimes it is 2 steps forward 3 steps back.
