Hello and welcome. My name is Scott and I am an experienced small animal veterinary surgeon, I will be very pleased to work with you today and will try my best to answer your question to your satisfaction.
Does look in any way like waht you are seeing in your dog's mouth?
hanging from back of gums. looks like long string like tags
Thanks for that, Boxers have a special problem as far as their gums go because the suffer from a type of gum growth called an epulis. It can take various forms and given your breed this is most likely what you are dealing with. The good news is that they are almost always 100% benign but the bad news is that the only way to get rid of them is by surgical removal. More info HERE
The best plan is to have a vet check Clyde over ASAP, conform the diagnosis and talk you through the surgical options.
Sorry I cannot suggest any home remedies in cases like this ....
thank you for your help will take clyde to vet today.
Good luck, in most cases this is a very minor problem. Regards,
