No medicine for arthitis but she does take medicine for her Cushings Disease and nothing else.
Joint supplements such as Dasaquin or Cosequin which are veterinary products specifically formulated for dogs are one suggestion. Quality control is a big problem with these products since what’s on the label is not necessarily what’s in the bottle which is why I mentioned specific brands. These are available on the internet. Also, fish oil supplements can be helpful since they have anti-inflammatory properties. Welactin and 3V Derm Caps are good veterinary products and are also available on the internet. It takes several weeks for these products to build up in the system, so you might not see immediate results. But once started, these supplements should be continued for them to be effective; you wouldn't stop and start them, in other words, like you would drugs...but you may already know this.
Another option would be Zeel which is a combination homeopathic that can be used in conjunction with other NSAID medications and has a very low incidence of adverse effects (LINK). Dose would be 1/2 tablet two to three times a day for a small dog....I'd go with three times a day for the first 2 weeks, then drop back to twice a day for maintenance.
Alternative therapies such as hydrotherapy, laser therapy, massage therapy and even acupuncture have been shown to be very useful for joint problems.
As to the question about when it's time to let her go, this is always a difficult topic and there isn't always a clear cut answer to this question in every case, unfortunately.
Thank you for the rating ad bonus; it's greatly appreciated. I also wanted to wish you the best with Tiny as you move forward with her situation.
