This is said to be a “Victorian painting” of two “golden retrievers” and a “boxer.”
I can definitely say that the dog on the right is not a boxer. It is a bulldog.
The other two dogs might be golden retrievers, but they are very light in the eyes.
And one is unusually light in color for the time period. Such dogs existed but were generally frowned upon within the strain that became the golden retriever.
I think these are retrievers, though, but they might not be “golden retrievers,” as in they are part of the same strain that became the modern golden retriever. There were strains of “white wavy-coated retriever” that existed independently of that strain, as did several strains that produced yellows and reds.
These two dogs really could be golden retrievers as we know them today, or they could be from another strain of wavy-coated retriever.
If anyone knows anything about this painting– year, artist, and the identity of these three dogs– it would be greatly appreciated if you could pass on this information.
