Convictions for animal neglect and cruelty rose by more than a third, in 2012.
A new RSPCA report also revealed the total number of animal cruelty convictions in West Yorkshire increased from 82 in 2011 to 126 convictions in 2012.
The report, today, revealed that animal rescues increased 10 per cent from 119,126 to 130,965 throughout last year.
RSPCA chief executive Gavin Grant said: “The RSPCA is leading the fight against a growing animal cruelty crisis.
“Our staff and volunteers show tremendous dedication but they are struggling to keep up.
“For us, prosecution is always the last resort. However, if there is evidence of a crime and serious animal abuse then we will take legal action to protect the animals.
“We also want to see judges taking these offences far more seriously.”
A successful conviction was imposed on the owners of a boxer-cross called Julia. She had been tethered to the handbrake of a car and left to starve almost to death.
An RSPCA inspector responded to a concerned call from a Bradford resident.
Sarah Briscoe said: “This dog was not only in a hot car but was so emaciated I thought she was dead.”
