went for a second opinion..

Hi Lauren How is Darwin??? btw it was lovely meeting you and him the other evening :D he´s a super little Pug Puppy.
it was obvious you were very upset :( so I hope he is OK and your are feeling better. xxx

Hope all goes well for you and Darwin I´m sure it will xx

Lauren, hope little Darwin´s op goes alright today and he is soon back home with you. x

Lauren my friends dog is a Boston terrier & Rascal (that´s his name) is very much alive now & causing chaos everywhere he goes xxx

was he really ok tina, what was his breed? xx

Don´t worry Lauren I know someone who´s 12 week old pup had a lump (not a histiocytoma) removed from his front inside right leg & he was OK he is now running around without a care in the world xx

oh hun at least you got a second opion .... try not to panic xxx

im fuming, the other vets told me it was a reaction, but its not. its quite obviously some kind of growth. im so worried he wont make the operation or aneasthetic x

i just googled it to see what it is http://vetmedicine.about.com/od/diseasesconditionsfaqs/f/FAQ_histiocytom.htm
