That little blue one reads rhino to me more than dog or fox. The head has that little horn nub and the body is way too chunky for a dog, so I am guessing it is one of those painted toy animals from the mid 1900s. Check the belly for maker marks once it is dry, that is usually where the ID hides.
The paint holding on like that after years in the dirt is a win by itself. The rectangular frame is likely a suspender or harness buckle, those turn up a lot around old house sites. And a wheatie right next to the critter is a nice sign that spot is worth going back to. Keep working that brush line.
