I realize in the grand scheme of things, this is not a big deal. Z is my fourth golden. The previous ones roo roo roo'd when they barked. Yorvit didn't bark at all until he was around a year. Z yodels! He starts with a roo, roo and then finishes with almost a hound-like howl. Is there something wrong with him? Anybody else with an unusual bark? He's a rescue, so I guess he could be mixed, but he sure looks golden, acts golden. But you know what they say, if he walks like a ???, quacks like a ???, then he must be a ???
