My dog is limping but it's one of those limps that is intermittent and I can't work out which is the affected leg!
Sounds stupid but it's one of those things I find hard to decide which leg is the problem and the more I look the more confused I get
If they go down on one side heavier is that the bad leg or is it because they are putting all their weight on it as the other side is hurting?

Panosteitis (sp) is often called wandering lameness, is this a young growing dog?

Alternatively could be a back issue in an older dog.

He is a puppy and it's not really noticeable indoors, more on very hard surfaces like pavement. I just can't decide which leg it is.
One paw has like a lump in it on his big pad, vet thought interdigital dermatitis but it's not irritating him as he doesn't lick or bite it. Been on antibiotics for two weeks and Metacam, now on topical antibiotic cream but no difference. But it's not this leg he's dropping down on!

If it is a front leg, get someone to move him for you and watch for the head 'nodding' the head goes UP when the affected leg goes down, it's the same with horses.

Don't think it works with hind legs but perhaps someone horsey can confirm/correct me.

Zuma had pano, ended up having 4/5 xrays sent to a referral vet who confirmed without needing to see him It was totally confusing as you just decide its near fore and next day its near hind or off fore!!!
Good thing was no treatment and he grew out of it.

Pano is most common in fast growing young dogs most often males and is slef limiting (they grow out of it).  It seems the lining of the bones gets inflamed.

Well I watched him outside and his head was bobbing all over so I gave up! His shoulder on the leg I think he is lame on looks different when he walks, bigger.
Vets again next week I think

With intermittent lamness I'd pop to the vets for some X-Rays, I had a young pup (5 months ish) once who kept randomly going lame in the end I had him x- rayed for pano and it turned out he had high grade elbow dysplacia.

I would say that the leg he's dropping down on is NOT the affected leg, because he'll be trying to take the weight off the sore leg as fast as possible - hence dropping down heavier onto the other.  At least that's what I do when one of my hips is flaring up!

Before you go back to the vets try and get some video to take in with you.  It may not be necessary, if the problem is obvious, but it's a good back up just in case.

Hopefully it's nothing too serious x

have attempted a video which does show him doing it. Its only really seen on hard outdoor surfaces. Maybe it is this digital dermatitis thing.

puppy had his paw investigated for the hardened extra bit of pad that had come up and not improved with antib's, this was the cause of his lameness the vet said. zero found inside unfortunately - we hoping for a foreign body so a cause could be pinpointed. it was just grisly stuff that has been infected. All washed out and now wait and see.

They are sending a sample as if it folliculits or interdigital dermatitis  it could just re occur and as he is so young maybe an immune problem!! i really don't think this is the case as I am sure all his feet would be affected, plus that diagnosis doesn't fit with how his paw was. He doesn't lick it and it wasn't oozing. He only licked when I put the cream on. it was like a hard lump which they said was infected follicles, but was obviously causing him discomfort when on very hard surfaces.

More antibiotics and just hope it goes away.

Get him on some Turmeric, Its very good for reducing inflamation. (and lots of other things) Mine have a couple of chicken turmeric treats a couple of times a day. I blitz 4 chicken breasts (Raw) and 2 eggs with 1/2 pint vigin olive oil, 2 eggs and 1/2 cup organic wholemeal flour add extra water if to stiff. you need a porridge consistancy and 2 teaspoons freshly ground black pepper in the blender till smooth. Then mix in 30 teaspoons organic turmeric and spread over a couple of flat baking trays about 1/4 thick(Line with greeseproof paper first) Bake in a hot oven till firm and turn over, bake again till nice and solid then remove and slice into 1 inch cubes. Feed 2 cubes at least 3 times a day.
It will support the ABX and can do no harm.
