Aw poor love, hope he's feeling better today and the lumps aren't anything to worry about
My Weimaraner was hospitalised last week for a day and a half after a snake bite and she panted and screamed and cried the whole time - I could hear her everytime I called for updates or visited her.. It's the first time she's had to be hospitalised since I've had her (she's a rescue) and I'm not sure how much of it was pain and distress and how much of it was panic about what had happened and the environment she was in
I was really worried about her but she settled down as soon as I got her out of there and slept for nearly 2 days - she'd lost her voice from all the crying and screaming too.
Hopefully he was just a bit upset and now he's home can start to relax and recover... gentle squidges from here
