Hello and welcome to Just Answer. My name is Dr. Larson and I'll try to help with Lucy's problem.
In most cases, when we have a licker like Lucy and have to resort to an E-Collar, the collar must be used untill the wound is fully healed. Unfortunately, this means she will probably need to wear it for another couple of weeks. As a wound heales, it begins to itch, much as it does in us. The licking is a response to the itch and an attempt to gain some relief. Until the wound is completely healed, it will continue to itch and we will battle the licking.
I had trouble connecting before. I further wanted to know if I could put a temporary breathable bandage on for when she has to have the collar off.
There should be no problem with covering it with a bandage when the collar can not be worn. A bit of topical antibiotic ointment may help speed the healing process as well.
also what would happen if she was left without collar would she lick until it became infected? Do i have to now keep collar on for the full 2 weeks as it is only slightly bloody and she has already had it on for a week?
It is unlikely that it would become infected with her licking. Dogs have surprisingly clean mouths. The problem that arises is that she will keep it irritated and the constant licking will prevent healing from occurring. I would recommend keeping the collar on until it is completely healed. Although there is no problem with taking the collar off if you can keep the wound covered, or can be with her and prevent the licking through personal interaction.
I certainbly understand your position. I really do not like putting my patients in E-Collars, and use them only as a last resort. No one likes them.
From your answer I suppose I have to check on her healing process and leave collar on as long as necessary.
There is no problem with taking the collar off, as long as you can prevent the licking. I would say, any time you are having personal time with her, take it off. It should only be necessary when you can not pay direct attention.
