Do Dogs Lymph Nodes Swell When In Heat?

It is important for pet owners and caregivers to have an understanding of a dog’s lymph nodes when they are in heat, how they work, and what can happen if they swell.

This article will provide basic information on canine lymph nodes as well as potential causes of swelling during this time.

Key Takeaway

• Dogs’ lymph nodes can swell during their heat cycle due to the increased hormone levels.
• Signs of lymph node enlargement in female dogs during heat may include swollen glands, tenderness or warmth to the touch and a decreased appetite.
• The underlying cause of lymph node swelling in dogs when they are in heat is due to hormonal changes that occur during the breeding cycle.

Do Dogs Lymph Nodes Swell When In Heat?

Yes, dogs’ lymph nodes can swell when they are in heat. This is due to a heightened immune response caused by the hormones released during estrus.

The most commonly affected lymph nodes are those located near the groin and armpits. However, other nodes may also be affected.

Swelling can be accompanied by reddening of the skin, pain or tenderness, and possible infection if not treated properly.

It is important to note that lymph node swelling should only occur while the dog is in heat and should return to normal when the heat has ended.

If your pet’s lymph nodes remain swollen for an extended period of time after their heat cycle has finished, it is recommended to seek veterinary advice as this could indicate a more serious underlying health issue.
