Sorry the visit was so traumatic Tonya - especially after you'd 'phoned in advance.
I'd say hang on til the treatment is concluded and Piper is fighting fit again - then I'd send a letter explaining what happened and howyou felt/feel.
Maybe the vet was having a 'bad' day - but to take it out on you -after a two hour drive (!!) is inexcusable - just plain rude!

{{{Hugs}}} to you and Piper - hope the furbun is better very soon xxxx Please let us know how his recovery goes.
