" Dog lump under skin issues are either a cellular mass, a tumor of the connective tissues or are deeply connected to the soft tissues of the dermal or skin layers. These may be benign fibroblastic tumors, nerve sheath tumors, vascular tumors or smooth tissues tumors. Lumps under a dogs skin are characterized by deeper roots in the soft tissues, a nodular appearance, are usually benign in nature (not cancerous, slow growing) and usually not painful. Some dog breeds like shepherds and poodles may be predisposed to these lumps. Lumps under the skin are usually attached to a root, which is embedded in the soft tissues. Due to a fair supply of blood and oxygen, these nodules can grow larger with the passage of time, also some lumps under a dog’s skin can mutate into a malignant form of tumor (cancerous, fast growing). It is therefore recommended that lumps be treated either surgically or preferably with drugs. "
On palpation, dog lumps can be felt under the skin, and may or may not painful. These may displace (move) under pressure and are usually attached to a base, with the root of the lump located deep in the soft tissues of the muscles
The appearance of the lumps and clinical examination is usually helpful in identifying the type of lump. Tumors under skin can be diagnosed by biopsy and with laboratory examination. Dog lumps under skin should be differentiated with those that occur over the epidermal layers (outer layers) of the skin by making note of any stalk or root which is embedded in the soft tissues of the skin or in fat under the skin.
Most dog lumps which occur under skin usually do not require treatment since they do not cause any systemic harm to dogs. Resection is only effective and preferred option for treating these lumps. Other surgical procedures effective are cryo surgery, electro surgery & complete resection. Resection should be made complete including roots & deep penetration. For complete eradication chemotherapeutic agents, adriamycin combined with cyclophoshamide, dacarbazine or methotrexate can be used.
Treatment plans should be determined by a veterinarian or a veterinary oncologist.
