Ms Alison McElwee, the adopter of a seven-month-old mongrel, is maintaining that the euthanasia of the puppy was not in breach of the adoption agreement signed with animal welfare volunteer Ada Ong on June 1.

In a seven-page letter sent to Ms Ong's legal team on Monday, Ms McElwee's lawyers from Stamford Law said that while Ms McElwee was supportive of making a donation to charities like the Society for the Prevention of Cruelty to Animals, this was done in support of a good cause and "not to satisfy any claim for damages".

Ms McElwee in her letter noted that she is also not acceding to Ms Ong's demand for a written acknowledgement stating that putting down the pup Tammy was a breach of obligations under the adoption agreement. This she wrote would "continue to perpetuate the untruths".

She was responding to a letter of demand issued by Ms Ong's lawyers from Allen and Gledhill last Thursday, which called for a $1,200 donation to a charity of Ms Ong's choice and a written acknowledgement from Ms McElwee due to breach of contract.
