I wormed my new filly Nov 2/11 (6 days ago), the past few days I am finding small bloodworms in her stool, is this the normal time frame for dead ones to start appearing in her stool? She was thin when she came here and this is my first time worming her, she also came with summer sores but the wormer I used treats both, she is 7 months and I was told she had been treated @ 4 and 6 months, though her condition is a bit rough right now she is eating well and her stool looks good besides the seemingly dead worms. How worried should I be? I am keeping a good eye on her and I am going to get her stool tested next week then treat again if need be in a few weeks but I don't think besides the obvious there is much else I can do. I have never had to deal with these worms so basically I am just looking for a good follow up procedure with them, and to know I am taking the right steps.
