My Dalmation Smells After Bath Is This Normal After An Anal Gland Expression?

Is this normal after an anal gland expression? - my dalmation smells after bath

Last Friday I took my (80. pounds, expressed 8 years old dalmatian) dog anal glands, because it leaking, and had a very unpleasant smell in the air. We took him to the vet and said he had a small infection, gave us antibiotics, everything went well for the first few days. I see on Monday is leaking again (not too big) When I lifted his tail to see if maybe some things that are excreted in the form of inflated anal juice and a small amount of what looked like pus, but still did not have that same smell this time.
The next morning I realized he had a little trouble going # 2, but he managed to make their trades, but I started to feel a little uneasy. Later that day I took a walk and went # 2usually
.
My question is: Is it normal to have pain or discomfort while the infection heals (which are still 4-5 days prior to the interception of drugs on the left) or an infection is the worst?
I also wonder if the reason why the costs are, because we have drastically changed your diet recently?

Whatever it has to focus a lot lately, if money was no problem, I would probably see the vet every day, I noticed something strange monkey .. have taken
