Cartrophen concerns

My dog was prescribed four Cartrophen injections. For the first injection, the serum in the bottle was coloured with a tinge of yellow. The following three injections were a serum of clear colour.

When I asked the vet she said it was just old stock. I’m concerned as treatment has not been successful. What should I do?

A case in joint

Hi,

I own an eight-year-old Toy Poodle who trains hard and competes at both agility and canine freestyle and has done since he was 18 months. He has never substained an obvious injury but this past year has been showing stiffness in his joints after training. This is usually in the evening and with a rest he seems fine by the morning.

I was wondering if anyone could reccomend a supplement for him as he is not currently on anything. Or do any of your readers have experience of other techniques helping, such as physio? I'd be grateful for any feedback.

Thank you.

Hello Dogs Today,

My Lab, Molly, is getting on a bit now and doesn’t enjoy such long walks anymore. A friend suggested adding supplements to her diet to ease her joints, but I’ve had a look online and there are so many that I don’t know where to start. Some make quite substantial claims that they can perform miracles too.

Can you tell me which supplements would help Molly along a bit, and how they work? If any readers could recommend any good ones I’d be grateful.

Thank you,
