We acquired a dog last month. She is the sweetest thing, already 8 years old, and DH's colleague has just come out of what sounds like a grim separation. He is about to move to a flat where dogs are not allowed.
Our dog had a dog partner in crime, who had been around the entire 8 years, but who died shortly before she came to us. So she has gone from a house with grown up/teenage children, mum and dad, and dog best friend to being in house alone for 10-12 hours at a time. So she was delighted to have us I think 
. The kids (older primary school age) adore her, and she gets a huge amount of attention, which she pays back a squillion times.
The "dad" told DH "she's fine, never had any problems/illnesses to speak of", but that was pretty much it. I've gone off at DH this morning because I've been asking for the name of their vet so I can at least get something from them...
The previous owner also swears her vaccinations are up to date, and that he did ticks/worms etc just before she came to us..and I have no reason to disbelieve him (apart from anything, DH is his boss, so he wouldn't want it to make work difficult I suppose!).
A week ago I took her to our local vet for a thorough check up, and discover that she has gum disease and a mammary mass.
The teeth can be cleaned today under GA, and they'll be fine as long as we keep on top of it now, but the mass is, according to the vet, a 50/50 thing.
We've ONLY had her 3 weeks, but coming home from the vet with her collar and lead this morning was pretty depressing, and I felt so sorry for her (even though she doens't know why, I know that).
AIBU to expect more of people? I'm going to just drop in that without any further surgery (if the mass needs excising), or x-rays (to see if the mass has spread to her lungs if it turns out to be CA), the bill is already 400GBP, for the GA, teeth cleaning, biopsy, histopath,
I did not hesitate to pay, obviously, but the whole thing just adds to feeling a bit shit. I know the kids have all gone off to flats/uni etc., but no one even wanted to say goodbye to her (she came to us for a trial weekend and just stayed).
I love her already dammit, and eldest DS is besotted. He understands that if she is ill, at least we've give her an amazing home for the moment.
Bugger and bother.
