Thank you, Nilsa!!! I guess its normal? Lol. I think when I’m done treating the melafix and primafix next week for his back, I’m going to treat with prazi-pro for deworming. The last comment said something about internal worms. I know it can be use as a preventative as well. I just bought a bottle off Amazon. Better safe than sorry. Not to mention, I always like having medications on hand. Thank you so much. I’ll keep you updated.
