16 week old border terrier right as rain this morning then just started being really horribly sick and now just vomiting white foam - am booked at vets at 4.20 this pm all up to date with vacs etc - would this jist come from eating something untoward as she eats EVERYTHING or should I be more worried - also she hasnt had any lunch yet - should I see if she wants some food?
Dill did exactly this when he ate something rank in a friends garden and then wolfed down her dogs special diet dinner. Once he'd purged everything from his system he looked infinitely brighter and was 100% better the next morning. You could actually feel his poor stomach bugling and he looked really woebegone.
It's probably just gastroenteritis, but she does need to see a vet. Don't panic if she seems otherwise well in herself. Definitely don't feed her, she'll probably need to be starved for 24 hours, but make sure she has plenty to drink and try to encourage her to drink so she stays hydrated.
The 'white foam' is just where she has nothing else to bring up.
If she starts to seem sleepy or lethargic or seem unwell in herself (other than maybe a bit fed up from being ill) then ring the vets back and ask to speak to a vet.
