It's a bit too close up to tell for sure but it looks a lot like some sort of Lonicera (honeysuckle). If it is, the berries are toxic to humans at least, but only if consumed in very large quantities. Generally, birds make rather short work of them. I'd not be overly concerned about the dogs: they tend not to graze on many berries and honeysuckles are very common plants throughout the country - there are many, many gardeners with dogs that grow this plant intentionally.
