Hi all, have any of you had a dog with bad diarrhoea following worming? My 5 1/2 month old pup has this a month ago, about 3/4 days following the Drontal based wormer and we didn’t think anything of it. 10 days of trying everything to stop it and we were successful. Roll on a couple of weeks later and he had wormer again yesterday morning and then terrifically sloppy urgent poo (on the pavement which NEVER happens with him) late afternoon. He’s a large breed so has to have more of the wormer, the larger he gets and he had 3 full ‘tasty bones’ yesterday. Could this be down to the wormer?
