dog gets wobbly

3yr old black lab was out in yard all of a sudden he got all wobbly as if he was going to fall lasted better part of a minute. any clues to what it could be thank you

Have you brought him to a vet yet? It could be so many things. From oxygen deprivation to muscle problems. Or it could be nothing. Talk to a vet and get a professional opinion. But do keep us informed what the vet says!

just the hind legs? all 4 paws?

Best check it out with your vet, just to be sure.

I hope its not a brain tumor or blood clot. Either one could be putting pressure on the part fo the brain the controls balance.

Was she near water? Might she have gotten water in her ears? Water in the inner ear creates a sense of inbalance. I'd check that and if it is not better, bring her to a vet to be certain.
