kinda sad about my first male i picked up for breeding. i got him off CL about a year & a half ago he was some ones pet & they were getting rid of him for free. he is a dumbo & was handled a lot so he has alway been super nice.they told me he was about 1 1/2 when i got him so i know hes old & had a long full life. but anyway about 3 months ago i put him with an unwilling female & she defended herself & cut his face pretty bad & that was the last time he tried breeding. now he seems to sleep more & more & his movement is getting more labored he seems to be not lifting his rearend when walking. he doesnt seem to be in any pain so im not sure what to do with him. I know some breeders would say hes no go & i guess as a breeder hes not. but should i just gas him so i know he isnt suffering or just let him live until he dies on his own?
