He's currently at vets with DH and for some reason I have a horrible feeling about it. He vomitted everywhere immediately after his breakfast this morning (then went down the corridor and was sick some more) so I didn't feed him again until tea time to give his stomach a chance to settle. He's seemed fine in himself, perhaps a little more sedate but he's quite a lazy dog in general so it's hard to tell. Fed him about an hour ago and he did the same thing, hence the vets.
The vet is giving him an injection to make him throw up, and has mentioned keeping him in overnight and a follow up blood test, but may not keep him in as he's super stressed and barking at everyone so they will see if he settles down. He's a very friendly dog but funnily enough he barked at the postman this morning which is unusual. He's also been sneezing a bit and has had a drippy nose which I've had my eye on for a couple days, and I think these things combined have convinced me there is something really sinister underlying.
He's 18months old and unneutered (planning to in next few months) if that makes a difference.
Could anyone talk me down?!
