I was out walking yesterday afternoon with my two dogs,the weather warmed right up,and I gave the dogs a lot of time in the water,and in shaded woodland,when I got home my older dog could'nt stand up,so I lifted him up,his heart rate was very high,and his nose was hot,he also had a darker than usual coloured tongue,he lost the use of his legs,at first I thought he may have eaten some poison,or was having a fit or a heart attack,it was feckin scary for me aswell as the dog,I lay him on the grass,and poured cold water on the insides of his back and front legs,after about ten minutes he was sick
