Don’t panic if you find a lump. The lump could be a wide variety of things, from a harmless spot or mole to a more serious, aggressive cancer.

How deep is the lump? Feel the lump and see if it seems to be in the skin, beneath the skin, or attaching the skin to the tissue beneath. What shape is the lump? Is the lump round or does it have an irregular shape. Irregular lumps should always be checked urgently by a veterinarian. How quickly is it growing? It is best to get any new lumps checked but if you are unable to get to a vet straight away, monitor the lump. Measure it weekly to see if it is enlarging. A rapidly growing lump needs urgent attention. Is it painful or itchy? If the lump is red, inflamed, or the dog itches or chews at it, this is an important sign that it needs checking urgently by your veterinarian.

Some lumps are judged to be of lower risk than others, these tend to have the following characteristics (although it should be noted some more serious lumps can also mimic these signs) : Round, growing on the skin, the skin remains free and not attached to tissue below, slow growing, not sore or inflamed. Higher risk lumps often have one or more of the following characteristics: irregular shape, rapid growing, deeply attaching the skin of the tissues beneath, inflamed itchy or painful.

Bone cancers, such as osteosarcoma, are acutely painful and the dog may be in discomfort when you touch the area. The area may be swollen and feel hot to the touch. Signs associated with bone cancer also include restlessness (as though in a lot of discomfort), a low grade lameness that gets worse rather than better, and loss of appetite. [5] X Research source

Symptoms tend to develop gradually with a slow loss of appetite and loss of body condition. This is also reflected in the dog taking less care of itself, and grooming less. This lack of proper grooming leads to a dull coat. [6] X Research source Sometimes the dog may also vomit on and off. Take careful note of the dog’s bowel movements, as this can give the veterinarian vital clues to what’s going on.

Of course, there are other common infections that also smell and are usually not serious (but do need treatment). It’s a good idea that if you detect a bad smell you should check in with a vet about it. [7] X Research source

Take note of blood in urine, feces, or vomit. Again, there may be an innocent explanation, such as cystitis or colitis, but these conditions also need treatment.

Seek a second opinion. This will give you a better idea about your options and will hopefully give you more peace of mind that your vet is making the best recommendations for treatment.
