today I noticed my pup Dexter have a weird hard red bump near his paw, anyone know what this might be ? kinda freaking out
I would definitely go to the vet asap! Any lump/bump should get checked out. I noticed a red raised lump on my black lab a week ago and took her to the vets, turned out to be cancer-mast cell tumour. I wouldn't delay.
Don't panic, could be from a tick or from a wound that formed a cyst. Seems everyone suggesting vet and of course that's the best plan. Does the dog run around in an area with a lot of weed growth, or sapling growth which could mean he runs into sharp pointed things here and there?
Meanwhile this page offers suggestions. There are many others that discuss papules: Causes of Solid-Appearing Lumps & Bumps on the Skin of Dogs
They say: Causes of Solid-Appearing Lumps & Bumps on the Skin of Dogs
Veterinary & Aquatic Services Department, Drs. Foster & Smith
"Dogs and cats can develop small bumps (papules) or larger lumps (nodules) on their skin. The term 'tumor' means an abnormal growth or swelling, and is often used to designate cancer. Often, the word 'lump' also brings the word 'cancer' to mind. There are, however, many other causes of lumps and bumps. The following table includes most of the conditions which result in solid lumps and bumps. The list is rather extensive, so you can understand why a quick diagnosis may be difficult to make and various diagnostic tests, such as biopsies, may need to be performed. The most common causes of solid lumps and bumps are color-coded gray in the table (some may be more common in certain geographical areas").
The graph is complicated. Search the term papule: "Deep inflammation of hair follicles; exact cause unknown; usually in young dogs; may see secondary bacterial infection". (like acne)
Or, "Fungal infection often transmitted through bird droppings; more common in dogs with suppressed immune systems'.
Or "Nodules" which could be "Epidermal inclusion cysts (infundibular cysts), which, "Result from body's reaction to certain skin cells".
