Milo has a huge lump on his left corner of his lip. When I press on it from the outside, he doesn't look like he's in pain. From the inside, the flesh doesn't look red. It's still pink. But, I cannot be certain of this as I only could get a quick glance. It's not ridiculously hard, quite squishy. He's not lethargic, depressed, drowsy, uncoordinated. He's quite happy to chew on his rope toy, and quite energetic as usual. He doesn't seem any different apart from the lump. There's no rashes that I can see.
He hasn't had his dinner yet, but he's eaten 2 puppy biscuits so far that is KNOWN. Not sure if any neighbours have fed him anything, though I don't think so.
My dad thinks it's an insect bite which will heal in time so he doesn't think it's necessary to take him to the vet. I know for some things, the bodies immune system is enough to fight whatever it is. But since it's unknown what cause it, I don't know if antibiotics are needed.
It slightly extends under his chin, and if dogs also have lymph nodes behind the chin like humans, then I'm worried it may affect his lymphatic system.
I haven't called the vet on the emergency line as I want some advice before I do so.
My dad said to let him eat his dinner and see if there are any complications then. He's having 2 chicken drumsticks, beef mince, organic yoghurt and spinach tonight. Will this affect healing?
EDIT: According to my dad when he walked him this morning, there was no swellings. When I came home at 6pm, is when I noticed the swelling. Mum let him in the house beforehand but didn't take notice of his mouth (not saying it wasn't there before already).
