OK my male lab "Handsome" jump in the saltwater pond after lounging awhile he went to get out and started acting very strange. When my husband came to get me he said the dog is dying. So I run out there to find the dog can't walk right and stumbling around. He then has some kind of fit. After not being able to find the Benadryl I popped him 2 aspirin and watched him. Well he seem fine now but what could have gotten him?
