I have 2 female, 5 yo pure bred boxer sisters from the same litter. The bigger of the two (other was the runt) had been diagnosed around 2yo with having a heart murmur. She (the bigger) has been acting strangely for the past few days & I have just notice 2 large lumps on her throat. 1 on each side. They move rather freely and seem to not be painful for her. She hasn't been eating for the past 2 days regularly and has developed a reaction in which she will randomly have these attacks where she swallows repeatedly as if she has something lodged in her throat. Her reaction is to want outside to eat grass. Obviously it must be these lumps that are causing her the discomfort. I am completely freaking out. She means the world to me. With the Covid19 Pandemic in full swing it's hard for me to risk taking her to a emergency vet in which has potential covid cases at their facility. I have read about cysts tht form on the lymph nodes that can swell with saliva. I am planing on taking her to the best clinic I can possibly find in the morning. There is no amount of money that I wouldn't pay for her treatment. I am trying to remain sensible but I am also devastated that I hadn't found these lumps sooner. How could I have missed them!? & how long have they gone unnoticed!?! I feel terrible. Any information is greatly appreciated.
