I was out for a walk last night and the dogs were mooch about and had run on something was tracking them one the collars made a funny noise never seen the warning before so run to where the dog was found my old bitch drown in a river thought she was dead pulled her out and revived her and got her to the vets , they think she’s been poisoned and had a seizure when running , I thought she’d struck at it and go knocked out on the rocks in the water , but she’s still in and not looking good , if it wasn’t for the tracker I’d never found her so quickly and she’d definitely be dead ! Been the longes
