Some do this.
Many swear by pineapple give some regularly as a treat it's supposed to stop them eating pooh.
If that doesn't work there's a vitamin suppliment your vet will sell ( it's not an rx) that stops it, guess it makes their pooh smell or taste bad to them.
Don't buy the pet store stuff apparently it has different amounts of the ingredients from tge vet version and isn't formulated for small breeds |
