I have a 10 year old Aussie Mix spayed female dog that is acting really strange. It started yesterday. She is panting since yesterday like she can't get cool(she is laying outside). She is not responding to commands as quick. She has been on gycoflex 2(helps older dogs with their joints) for about a month. She just isn't herself at all. Can anyone please give me some answers or advice?

There just isn't near enough information for anybody here to tell what the problem is. She needs to go to the vet. If you can't get her in yet this morning, I hope she will be OK until Monday.
