Thank you for your help. And this is hitting our famaley hard my husbands disabled and that's his buddy but our old girl is acting really tired all the time and she don't want to be bothered and she's just not herself going to take her to a vet
This sounds serious and needs to be addressed by your regular veterinarian immediately. Bug bites do not cause the signs you are describing and mammary cancer needs to be assessed immediately if you are going to have any chance of correcting the problem.
