My dog has tiny scabs all over body. She only goes outside to potty and is 13 years old with congestive heart failure. Should I be worried?

Hello and thank you for posting your question on Petco Pet Education Center, formerly Petcoach!
Sight unseen, it can be hard to say exactly what the issue may be, but I can offer a few possibilities.
One possibility could be an allergic reaction to an insect bite or sting if she has developed these lesions in the last 24 hours (recently). Another possibility could be an allergy to pollen, grass, or another environmental allergen. Sometimes dogs can be allergic to carpeting or certain upholstery. Lastly, the scabbing could be caused by mites causing mange or a bacterial or fungal infection.
To directly answer your question should you worry is hard to answer in this case. I would have to talk with you more to get a better idea. Environmental allergies, bacterial, fungal, or infections cause by mites are all treatable and are generally not cause for alarm unless the problem is very severe.
I hope this helps answer your question. Feel free to request a consult with me and we can chat further.
Best to you and Lilly!
