I thought the Springer Spaniel was a perfect example of a Springer Spaniel. I would have gone with the Springer.
But, to be honest, the lines, head, attitude of that Beagle was 100% pure Beagle. Besides, I like Beagles, and although I have a Ridgeback, I’d readily pick up a Beagle. (The wife wants a German middle-standard poodle, and I already have a dog. Lol.)
Poodles come in three sizes. Standard, above 15 in. Miniature, between 10 - 15. Toy, below 10. Europeans have one called a Moyen, which is a small standard. I have a mini right now, but if I can talk the hubby into another, I think I might go with a toy. I guess I am lucky he let me get just one!!! Good luck to your wife.
