We had to take Millie to the vets at the weekend as she was having difficulty walking and fell down a few times, she started to limp/dip a little on Thursday so i gave her some metacam and by the afternoon she seemed a little better and the same on Friday but on Saturday she seemed worse and as she has a sensitive tummy i cant give her to much metacam. Any how the vet says it is Arthritis and as given her some tablets called PREVICOX, she as given us a 10 day supply and then we need to go back. Has anyone else's dog had this, did it help or do you know of any other thing we could try just in case this does not help. She has been on a herb fusion for a while now and i believe it has worked well for her, but obviously she must need something a little stronger, she will be 15yrs in April.
