@Faith-and-Hope @Snowie @Shaz51 Have been to the vet. Clover still has some redness in her mouth but we are going to treat it for the meantime with teeth cleaning wipes. I will have to do it once a day but it will be worth it if it helps. It seems if she does have an allergy then it is minor at the moment and it is certainly not causing her any issues - especially with eating - so we may have dodged a more radical treatment ie. all her teeth out. She has  settled back in at home already - as if she had not even gone out 😛 I am going back outside to do some more digging as despite a few drops of rain earlier, that is all we have had. It will take a few days to do but will be one big job I had planned these holidays.
