On the strangest things eaten by dogs (‘She’d consumed a kilo of sand’: 11 Guardian readers on the weirdest things their dogs have ever eaten, 15 June), back in the 1960s, friends of mine in Hampshire had a dog, and they later got a kitten, which loved chasing marbles.

The dog became rather slow and poorly, so was taken to the vet. An operation released 100-plus marbles accumulated in her stomach.

The dog had been swallowing them out of envy of the kitten, which was getting all the attention.

My dog’s list includes: the tube of nipple cream that I bought a week before giving birth; my underwear, extracted from the lidded laundry basket (which she later shat out that evening); a brand new mouth guard that the dentist made me promise to wear every night (leading to me also using the excuse “my dog ate it”); and a rock.

When my lurcher, Rodney, was a puppy, he ate some plumber’s tape that my son had left lying around. I only found out as, when I arrived home, there was some hanging from his mouth. Luckily it pulled out easily.

As it turned out, I’d not got all of it. The next morning on our walk he decided to get rid of the rest of it. Unfortunately he needed my assistance. Standing on the pavement, pulling out yards of plumber’s tape from a dog’s bottom is … different. Oh well, it did make me laugh and he didn’t need a vet.
