I have had beagles with stomachs of steel. This beagle, now 2 ½ has had a problem from day one with people food. It is the strangest thing and the vet has been of no use; granted they have not seen him in this actual state. He will have human food – even just a wee bit – and the next day he is lackadaisical, will walk into walls because his equilibrium is off and looses control of his legs. We need to pick him up, and he usually urinates himself – sometimes he vomits. He is shaky and it is almost like he is having a seizure. It takes several hours to a day or so to get better. This can be a piece of beef as small as a fingernail. Now, he can have water based veggies with no problem – like a carrot, lettuce or celery. Has anyone ever had or heard of any such thing? Vet says he should be able to handle people food… No kidding!
