We have 4 dogs, 3 miniature schnauzers (ages 3 to 5) and one small mixed breed (age 5). We were finally able to cut grass today after a lot of rain. Everything was fine with them all day. This evening when going to crate them, our youngest schnauzer and the mix could not stand on their back legs. They don't seem to be in pain and there are no other symptoms that we can detect. The other two dogs are fine. Is it possible they found something in the yard that did this? I did uncover some mushrooms while mowing. If so, is is permanent? Any help or advice would be great. I cannot really afford a vet bill right now, but will take if it is necessary. I am hoping this will wear off. Any advice would be greatly appreciated. Thanks. P.S. I am located in Colorado Springs, CO if geography might play a role.

Do you put weed killer on your grass or is it built in to the seed or any fertilizer?

With things like this it's always best to go to a professional who can examine your dog. We have no idea what they may or may not have gotten into, and anything we say is just a best guess. It could be poisoning, or it could be neurological or they could have pulled ligaments or torn muscles while running and playing. They could have injured their backs from jumping and playing. There are just too many what if's for us to even guess.

Sorry we can't be of much help, please see your vet and keep us posted. All the best and good luck.

My first thought is mushrooms, as well. No yard mushroom is considered 'safe' to eat since there is such a wide variation is what kinds are possible to find. In fact, the universal recommendation is to clean all yard mushrooms and toadstools out since kids and pets can't be trusted not to 'sample' one.

My suggestion, since I have nothing other than guesses for an answer, is to get hold of your vet first, then possibly the Extension Service at CSU, for suggestions and possibly directions to the closest county office, in case they suggest taking samples of the yard crop of mushrooms in for identification. Without an ID, it is pure speculation as to what has happened.

I hope this is of help as well.
