just got back from derm and asked her about pseudo cushings and she said that is alopecia X
Alopecia X
she said no way that is what dd has going on as it is very distinctive hair loss and does not run in yorkie breed as it is mostly runs in pomeranians. She thinks dd thyroid is low and meds need to be upped so we are making appt for thyroid and blood panel. She said if it is not thyroid related which she feels strongly it is due to the way it is thin all over which indicates hormonal imbalance then it is from steroid use as steroids can cause hair loss. She said if it was due to staph infection then it would be more of a blotchy hair loss not a thinning all over in her opinion.
she recommended again the hyposensitization shots

with varl lab doing the testing and it is 12 things that go into the vile and she gives me the results i investigate what is most in my area then she makes it up in viles 1 and 2 and if i want she will dilute it further to be 0,1,2 so thinking i may have to give it a shot

only thing i have not tried and safest long term and works 70% of the time. She said if it makes her worse we stop as that is my biggest fear

She said if it is not hair loss from thyroid and due to steroids then i really need to consider it as dd is only 6 and has a good 10 years of possible life span - i am going to think further about it but it has weighed on me for 3 years - Anne was suppose to go first though lollllll
Hope this helps as i think you said yours had a bacteria infection and hair is growing back and his looked more blotchy than dd i think from that first pic you showed and you said thyroid panel was fine so not thyroid related.
The bummer is 3 weeks on antibiotic and staph is still not gone so we have to continue for 2 more weeks
Thanks Again linda for recommending the pills for clinda as those are a God send for me and she is not itching on them like she was on the liquid so something in the liquid they use made her more itchy and someone on my allerdog group said they use corn starch in it which would not surprise me as that stuff is really sticky and it would get in her hair as she spits it out

so thanks again
