Hi all I just picked up my Aussie ( Australia Shepherd )from the vet, they spayed herI get all the instructions and the pain killers they sent her home with. On my way home in traffic the vets assistant calls and says the vet meant to tell you that the Deramaxx we gave her for pain can and has been known to cause the following; -kidney damage and secondary effects on the heart -liver damage -gastro-intestinal ulceration "Okay thats all I wanted to say".. and hangs up the phone. I try to call back without answer. Has anyone used this drug for their pet or can I give her another OTC such as Tylenol or something. I know many of these things we take can be harmful to dogs but the assistant almost seemed to be warning me and I cant get a hold of anyone now.
