Please call Merck and post on fido savvy.com. Merck is saying they don't know of any issues with this drug but I'm finding plenty and they need to know about it. https://secure.merck-animal-health.com/company/Email_Us.aspx?SiteID=457&st=py1ucszdbcvkbru4ead2x1yb
I have a Yorkie with bladder crystals. She was in three homes in three weeks and she was hyper but, after 15 days on Incurin she began "herding" my other Yorkies. We didn't think much about it but after 30 days she is aggressive and literally hunting my other female Yorkie and attacking her. We are stopping the Incurin and have her on doggie downers to try and manage her behavior but she is still hunting her. I, too, would like to know if there is a time when this will stop. It is like she is possessed. There is nothing about this on the label of Incurin but there is something on the Incurin testing site about three dogs having to be euthanized due to aggression. Shouldn't people be warned of this issue? Thank heavens she's not a Mastiff!
