Only DOTD is Blocked at my office!?

Just wondering if anyone else is having difficulty viewing the DOTD like I am on my office computer . . . the powers that be have put quite a few new restrictions on our computers, but I don't understand why I can see the Pet and Cat, but when I click on the Dog it is a "blocked website". I have POTD on my favorites, and as always when I click, it brings up the POTD main page, with the cat and dog along the side, but as of yesterday now there is no small picture of the dog, and I even tried to access from different areas of the website but to no avail. Maybe there is new and different code used only for the DOTD that my work system is picking up and blocking?? If so, I hope it is not applied it to the Pet and Cat or else I will be missing out on way too much to keep up with since I can only turn my home computer on once or twice a week due to home obligations . . . I am perplexed. :confused:
