Hi Mucker, its so fun to get a puppy!! I'm just glad for you it's a small dog. I have a yorkie and she weighs 8 lbs.
My incisions are sore and lumpy feeling too, and so thick feeling. I have soreness in my biceps by late afternoon everyday. I was told it's muscles compensating for the loss of the pec minors and its to be expected.
I'm glad you're feeling somewhat better. Take it slow and enjoy those puppy "kisses".
Ihtos
