I feel so sorry for you...my dog is getting on abit and she had an absess on her **** gland...and on saturday she was shaking and couldnt sit down and she's lost soo much weight, so my mum took her to the vets and i was in floods of tears cause i thought she was going to be put down(she didn't, she's getting better but still getting really old and it's upsetting)...i dread the day she goes...because i feel so guilty for not being patient with her.
