Q Why do male dogs pee against vertical objects such as trees or fence posts, without actually leaning against them?
SB, Surrey
A For dogs, the vertical surface acts as a visible landmark for scent marking. Other dogs know to check such objects for traces of a passing dog. Most dogs are as happy on three legs as four so they have no desire to lean on anything.
Q We have inherited a 10-year-old collie; she has to be ambushed to put her collar on and she refuses to walk anywhere. Is she too old to get used to a lead now?
CGC, via email
A She can still be retrained, but you must be patient. A head halter often works better than a collar – give her treats and praise as you put it on, and take it off after a minute. Repeat this several times daily. Once she accepts it, start with 30-second walks. Dogs are never too old to learn new tricks.
Q My cat has daily drops for arthritis and needs a check-up every six months. The cost of this, along with routine care, such as flea prevention/wormers, adds up. Do you think vets’ fees discourage people from properly looking after pets?
KH, via email
A Animal medicine regulations aim to achieve a balance: ensuring that medicines are not given inappropriately while not insisting on unnecessary check-ups. If anyone has financial difficulties, it’s worth talking to your vet about budget options.
