Bonnie Scottie not walking properly

Question
Dear Karen
my scottie (Bonnie) is just 2 1/2 years. She has uptil recently been fantastic on a lead. She adores going for walks but our only problem since she came and finished heat is that during her heat she began to refuse coming home from her walk. Once I turned to come back from walks she would sit down. I thought this was just because she was in heat but she is now walking quite slow and stalls when I try to turn around en route home.  I have to wait till she is ready to walk. I don't want to pull her. She seems to be carrying some kind of lameness on the right upper thigh. I had her checked by vet the other evening but he said he could'nt see anything apparent!  He walked her but as she hates the vet she almost ran out the door once he started to walk her so did'nt see what myself and my husband have noticed. The vet checked her out temperature etc, hind quaters and found nothing.  She is eating really well but I know her 'form' is off ever since she came into heat.  Should I bring her to a different vet?  I got the feeling my vet thought I was fussing over her, I'm not but you know when a dog has gone from being really perky to 'down' in herself. I have a Westie (Clyde) of 3 1/2 years and normally Bonnie is a frisky and lively as Clyde.. not so these past 4 weeks hence my concern and there is a slowness in her walk. What can you suggest I do ?   

Thankyou

After having dogs shown in agility by my daughter the last seven years, I am quite adamant about the fact that whenever one of the dogs comes up with what I would consider a structural problem (skeletal or muscular), it goes to a chiropractic veterinarian. Regular veterinarians can rarely figure out what the problem is, and if they do find the area that is causing a problem, they simply slap a bandaid on it by giving pain-killers rather than trying to fix the problem.

Hopefully, you live in an area that has a chiropractic veterinarian.

If you go over Bonnie carefully, you might be able to find an area that is warmer than the surrounding tissue. That would most likely be where the problem is, and it should be iced down for about twenty minutes a couple times a day.
