I've just recently started learning more about dog health (beyond care basics) and in particular, I've only just learned about vaccinosis, and now I'm a bit curious about it. (Luckily, our routine vet keeps up to date on things and has been recommending infrequent vaccinations for years, so our dogs haven't suffered.)

In particular, I'm just a bit curious about a situation with my newest dog. I adopted him about a month ago from an animal shelter, and a day or two before I adopted him, they gave him the full whack of vaccinations for EVERYTHING. Given that he's 5 or so and looked in reasonable condition- not starved as if he'd been neglected- it's entirely possible he was already up to date with everything. (I mean, for all I know he'd gotten his scheduled rabies shot two weeks before he ended up at the shelter, you know?)

About a week or so into having him at home, he went through several days of unusual behavior. At the same time, he had a couple of incidents of vomiting/loose stool, which we attributed to shifting him to a new diet. He is generally a very friendly, very tolerant dog, but for those few days he just seemed very repressed/depressed- not to the point that we were concerned, but significant enough that when he improved, it was very noticeable that he'd been behaving oddly (for him). He was also having quite agitated sleep- lots of very active dreaming. He also improved VERY rapidly, basically overnight, back to being much more like the dog I originally met at the shelter.

At the time, as I said, we attributed these things to various aspects of being in a new environment, but I'm just wondering now if in fact it may have been related to the vaccinations. (He seems fine now, so I'm asking mainly for my education for the future.)
