I regularly buy this product and it is very effective and value for money
My dog just won't take these - just ignores them when buried in food and pushes to one side. Eventually have to put the half pieces down his throat - what fun that is! Tried for 2 treatments now. Used to use Pro-wormer with no problem, but seems no longer available.
My dog hates all worming tablets and these had to be disguised in ham to get him to take them. Like being able to break in half to control dose. Did have a bit of upset tummy after but that's pretty usual with most brands. Worked and good price.
