I'm a big fan of Warwick Animal Hosp in Cranston. They were wonderful when I lost my 22 year old kitty a few years ago, they do great with my current nervous-nellie dog, and they've just been rock solid every time I've needed them. Not the cheapest by far, but the service and staff quality are worth it, imo. I'd recommend avoiding Hoffman, because they turned the horrible experience of putting down a beloved dog into something much worse - the medication caused a final, fatal seizure and the vet's reaction (standing there) was to shrug and say "oh, yeah, that happens sometimes." Inhuman.
