So yes, a Brittany spaniel can have green eyes, although it's not the most common color.
Here's what you should know:
* Green eyes are not a disqualifying trait: They are perfectly acceptable within the Brittany breed standard.
* The shade of green can vary: Some Brittany spaniels may have bright green eyes, while others may have a more muted green.
* Eye color is not always an indicator of health: While some eye conditions can be associated with certain eye colors, green eyes are not inherently linked to any health issues in Brittany spaniels.
If you are concerned about your Brittany spaniel's eye health, it's always best to consult with a veterinarian.
