Highly recommend 5 This has improved my Labrador mobility & kept him pain free. I have noticed an amazing difference in him.

My Jake has been on Onsior for 6 weeks now and I have noticed a great improvement. Thankfully he is not allergic to this medication unlike the previous painkiller he was on which affected his paws which in turn meant he didn't want to walk on hard surfaces. He has also got used to the taste quickly which also helps when it comes to administering the tablets.

My dog has been prescribed these on going and they are around half price via VetUk than the vets which long term is a saving. They are helping my dog so a winner all round.

Very good for Sunny's arthritus, the difference between him taking it and not taking it is amazing

Definately has helped my 13 yr old dog with skeletal pain in his back. Yes the worry is the long term side effect of taking any drugs on his kidney's and liver. 6 monthly blood tests to keep track.
