Chihuahua 
When I was a baby I was given a Chihuahua puppy by my Pop so guess it’s no real surprise that they’d end up being my favourite breed 
Unfortunately though he was murdered by my Father when I was 13 rather then take him to the Vet he decided to take him into his shed telling me to wait outside when he came out he was dead wrapped in a Blanket 
From memory my father claimed there was a lump on his head supposedly of which I never saw and my Father decided to burst it giving him a heartattack.
