Ok! So today while I was at work my girlfriend was taking care of louie they played outside and she fed him some watermelon.. after she saw his cheeks get really red, hard and his eye get swollen.. she saw some itchy spots on his belly and scrotum.. she panicked not sure of what may be going on with him.. she gave him half a pill of Benadryl, at that point she called me and I told her to take him to the vet IMMEDIATELY.. I just picked him up not too long ago he looks so much more better vet told me that if she had waited a bit longer his neck may have swollen shut.. she also said he was burning up with a fever I asked if an allergy screening would determine the cause because as a concerned pops i just wanted to know what it was.. i didn't want to let him go outside anymore.. she insisted that it could have been anything and that an allergy screening wouldn't help as much as it happening again and having a better idea of what is causing that. Has anyone ever experienced this..? I wish I was present while it happened but my girlfriend claims it happened out of nowhere.. i really don't want to say that it could have been the watermelon.. he's had watermelon before and been just fine. Vet also said that it may have been a bug bite that cause the reaction.. Thoughts? Thanks.
