Last time I wormed my puppy, later that evening she had blood in her stools & proceeded to do for about a week. I phoned the vet & they said this was a normal reaction to worming.
So, I bought some more Dontral Plus for her because it has been a month now. She threw up yesterday but has eaten & been okay other wise. Her poo was looking a bit pinkish too - I put this down to her food, some of the kibble is red. Last time I trust the OH to buy dog food for me. Anyway, so I wormed her this morning (I was quite proud that I got her to take the pill) & just now she has quite a bit more blood than last time in her stools. Is it possible for the worming tablet to affect her within the hour??
