I don’t know if it’s just luck but our two Sprockers seem to have iron stomachs.
Whole loaves of bread, advent calendars, big chunk of Christmas cake, whole toddler poo (straight in there and gone as she stood up off the potty!) not even flinched. Whole kids socks pass straight through and out the other end (we don’t try to reclaim them). The older one even consumed the netting from a beef joint – came out the other end ready wrapped.
The vet will most likely take a conservative approach to any diagnosis. Not worth the risk of it ending up going wrong. The owner may accept it as part of life and move on or might try and bring down the whole surgery in lawsuits.
My Grandma (late 80’s) is, and always has been, a worrier who believes most thing she reads in the Express and watches on This Morning. So in her mind the slightest whiff of chocolate or raisins and the dog will keel over there and then. She’s also had a single glass of red wine every day for the last 20+ years because she once read it was good for her heart. To be fair, that one seems to be working!
