When my youngest doxie, Blue, was but a tiny pup of about 4 months,( and about 5 pounds) she ate an entire tin of Honey roasted peanuts and cashews. I had left it on the coffee table..with just the plastic lid between the nuts and doggie bliss.
Her poor belly was distended right out like a balloon. I dont think my older doxie ate a single nut ( which is funny cos she is usually the trash picker, food stealer). Poor Blue was passing peanut poops ( looked like those planter's nut rolls) for two days. Maybe that's why she is very cautious about what she eats now...
