A shock number of animal cruelty complains have come from the Lockyer Valley and Somerset in the past 12 months, despite RSPCA investigators working a "full throttle" year.

Across the region, 533 complaints were made to the RSPCA about animal cruelty in the Lockyer Valley and Somerset region, RSPCA data revealed.

The number of complaints marked a decline on 2019's data, which revealed 672 reports of animal cruelty in the region.

In both years, Lowood has recorded the most complaints - 42 for 2020, and 53 for 2019.

For 2020, RSPCA inspectors investigated 17,146 complaints across the state about animal cruelty and neglect, while ambulance officers attended 29,072 rescues.

RSPCA Qld spokesman Michael Beatty said there was a "glimmer of hope" following the case numbers declining from 2019 to 2020.

"It's still bee incredibly busy," he said.

In the Lockyer Valley, Gatton man Jack Saunders was charged and fined $3000 for kicking a pigeon to death during a drunken night at the Royal Hotel in Gatton's CBD.

Father-son dog breeders Harold and Keith Moorhead were sentenced to a two-year probation after they were found keeping 152 animals in poor living conditions at their Churchable property.

The Moorhead's were originally busted in 2019, but the case was finalised in the Ipswich court last year.

Mr Beatty said the worst and most distressing case of 2020 involved a kitten that had firecrackers taped to it and set alight, along with a dog that was shot in the leg that later had to be amputated.

Ambulance rescues also included a wallaby down a mineshaft and ducklings that had hatched in a homeowners chimney.
